Comprehensive Guide about Spring Toggle Latch

Work holding and the need for spring latch is an often ignored part of the machine work.

Normally, workers and operators put materials into industrial equipment for hold and stability.

Nevertheless, the proper hold is vital for safety and precision.

When materials slip during a machine process, there are more consequences than having an off-specification product.

Yes! It can cause great harm!

Finally, when work holding fails, it’s not typical for machines to become damaged and injuries to happen to operators.

That’s why it’s crucial to assess and understand the different kinds of work holding industrial equipment and hardware as well as their applications.

And one of this industrial hardware is spring latches.

CHAPTER 1: What Is a Spring Latch?

A spring latch is locked with a spring compression, so it is not released because of vibration.

Spring Loaded Toggle Latch

Its arm is made from stainless steel thus it’s rustproof and tightening strength is sufficient.

A strong spring is made for the vibration equipment.

These spring toggle latches are widely utilized in different applications like:

  • Automotive
  • Industry
  • Ventilation
  • Air conditioning
  • Industrial enclosures
  • Specially-equipped vehicles
  • Industrial machinery
  • Machine tools and containers
  • Trucks
  • Automotive
  • Off-highway vehicles
  • Construction equipment
  • Cases
  • Garden equipment
  • Metal cutting
  • Machine tools
  • And more!

Spring latches have two different materials:

  1. 304 stainless steel
  2. 201 stainless steel

Spring latches finish could be nickel plated, zinc plated, chrome plated and tumbled for stainless steel.

Draw latches work on the principle of drawing two objects together with tension.

The major components of a draw latch assembly are:

  1. The blade

It’s a hooked plate or a wide made loop

  1. The Keeper

It’s a hooked plate which gets the blade

  1. The hinge

It’s the one that allows the open and close movement

The tension is made when the blade is hooked to the keeper and clamped down.

For standard draw latches, the tension is free if the latch is rotated to a vertical position.

It’s applied once the latch is rotated to a horizontal position.

These toggle latches are complemented by a wide array of matching strike plates.

They are manufactured from either stainless steel or cold rolled steel.

What’s more:

They also feature countless options including vibration proof models, like the adjustable latches.

That’s to offer padlockable, key lockable, and gasket pull up types.

A few have a secondary locking feature to avoid accidental unlocking.

CHAPTER 2: Understanding Spring Latch System

When we talk about products, the easiest and fastest solution that has the highest possible quality is normally desired.

This fast-fix outlook goes for almost any industry, small or big.

One small and simple item which can provide fast solutions is a latch.

A spring-loaded latch is a latch which utilizes the spring to actuate the latch.

That aids to return the bolt to a default position if not in use.

Let us explain:

It’s typically in the closed position.

If the latch isn’t in use, the bolt is pushed forward engaging the keep until someone opens it.

The bolt is pushed back from the spring eliminating the bolt from the keeper.

A spring latch system is quite simple.

In the simplistic structure, the size can differ somewhat a bit while the overall design is more likely to be across applications.

A metal frame holds the bolt.

Around the bolt, there’s a spring that’s always fixed to push the bolt to the further out position.

A variety of manufacturers makes spring latch system locks.

They have comparatively different designs, but they serve the same function and provide similar security measures.

A single-latch lock is spring loaded.

They feature a rounded metal ends which project from an open door.

The spring latch retracts as it glides past the door frame and discharges.

It mounts securely within the hollow plate on the attached door frame.

Where do spring latch systems make your day-to-day life easier?

Have you desired something you were utilizing this kind of latch system?

Are you now interested how does a spring latch work?

Continue reading to know more.

CHAPTER 3: How Does a Spring Latch Work?

It’s already mentioned that there is an abundance of latch types which are regularly utilized in all aspects of life.

However, a spring latch is the type of latch that stands out.

This particular type has some attributes which other latches don’t make it desirable in some cases.

Can you guess what it is?

The Structure of a Spring Latch

Once the bolt is pulled, the spring compresses. It disengages the bolt from whatever it is holding together.

Once released, the bolt fires forward to its resting position along with a decompressed spring.

A simple way to picture how a spring latch works is like launching a pinball.

When a quarter is put into the machine, there’s a ball that pops out and rests on the bolt.

However, if you pull back the bolt, you’ll notice a tension from the spring surrounding the bolt.

If you release the bolt on the pinball machine, there’s a forward force exerted into the ball.

That makes it launch into play.

Compared to pinball machines, spring latches are utilized to hold two (2) components altogether, either closed or open.

The job of the latches is to ensure neither component is moved from that preferred position.

The spring latch works the same to a deadbolt, but there’s a difference.

As an alternative to the push-pull action needed for a deadbolt to engage and disengage, one movement is essential.

That’s because the spring performs the rest of the work for fast detachment.

Spring latches can be utilized in a wide array of applications.

It can be from industrial, HVAC, railway, vehicles and machines, and a lot more.

The fast release mechanism of a spring latch makes latching quick and simple for any applications which it’s utilized on.

CHAPTER 4: Common Materials Used for Spring Latches

Durability is a crucial consideration in your spring latch.

The materials they are typically made from are the highest quality metals which do well outdoors and can endure the elements.

You will find a price difference between every substance.

In this chapter, we will give you the pros and cons of every spring latch materials like brass, bronze, aluminum, iron, and spring latch stainless.

Brassfor that Aged Look

Brass is one of the materials that is least conventional utilized in outdoor latches.

But if you want the look of the colonial design, it’s a perfect option.

It’s a heavy metal which feels hefty in your hand.

It also adds an excellent design element to your door.

The only possible drawback to this spring latch force material is that it will tarnish over time.

While you might enjoy its aged appearance, it’s crucial to maintain the surface.

After all, you want to keep the surface to preserve the life of the device.

Stainless Steel for a Modern Look

Spring latch stainless steel is somewhat a distant cousin to aluminum.

Stainless steel has the similar appearance to aluminum, but it’s a much heavier metal.

It’s strong and less likely to bend, warp and dent under temperature or pressure.

While it’s a bit costly, it’s a good material for a durable latch spring force.

It’s normally utilized in contemporary and modern designs.

It’s rust-resistant, and you will notice it in its raw silver form.

Powdered coated models are accessible.

It offers them an added layer of protection if you reside in a corrosive environment such as near the beach.

There are two types of stainless steel spring latch material:

  1. 304 Stainless Steel

304 stainless steel is the most typical form of stainless steel utilized around the globe.

That’s because of its superb corrosion resistance and value.

It’s composed of 16% and 24% chromium and about 35% nickel.

It also has small amounts of manganese and carbon.

The most typical form of 304 stainless steel is 18/8 or 18-8 stainless steel.

It comprises 185 nickel and 17% chromium.

304 can endure corrosion from the majority of oxidizing acids.

That durability makes it easy to sanitize.

That makes it perfect to use for food and kitchen applications.

It’s also typical in buildings, site furnishings, décor, and even hardware like spring latches.

The only disadvantage of this material is that it’s susceptible to corrosion from chloride solutions.

Chloride ions can make localized zones of corrosion, known as “pitting.”

It can range beneath protective chromium barriers to settle internal structures.

  1. 201 Stainless Steel

On the other hand, 201 is a genuine chromium-nickel-manganese stainless steel.

It was made to conserve nickel.

201 is the lowest cost option to traditional Cr-Ni stainless steel like 304 and 301.

The additions of nitrogen and manganese substitute nickel.

It’s non-hardenable by thermal treatment.

201 stainless steel is non-magnetic in the annealed condition.

But it becomes magnetic if cold worked.

Bronze that Ages Well

One of the costliest materials on the list is the bronze.

It’s a significant material which ages well.

It’s a famous option for those establishments with high-end design taste.

It offers a beautiful look, and it feels dense to touch.

The majority of spring latch designs are made with an element of imagination.

They feature old-world, contemporary and traditional elements.

The metals ages well and it does not need a powder coat to finish it.

It eradicates the risk of chipping or the necessity to refinish it over time.

Aluminum for Durability and Functionality  

If you are worried about corrosion or wear and tear, aluminum might be the perfect material for you.

It is both durable and lightweight.

It has a natural resistance to corrosive elements.

It can also be utilized in any environment.

It’s a much brittle material compared to iron spring latches.

While you can buy designs in the conventional shiny silver color of the metal, aluminum spring latches are often powder coated.

They are coordinated with other spring latch hardware in more rustic colors such as black.

Typically, aluminum spring latches are the least expensive of the list.

It won’t limit your style options.

It’s made into the modern, traditional, antique and old world designs.

The metal is both functional and attractive as well.

Iron for All Door and Gate Style

Iron is the most commonly used spring latch material.

It’s crafted in a wide array of ways including traditional, colonial, antique, and old-world styles.

Manufacturers like Roche use both wrought iron and cast iron as it has a huge and stately look.

That looks great against your fencing.

The metal commonly gets a powder-black coating to offer it a layer of protection against the elements outdoors.

However, it might not be a perfect option if you reside in a place with many corrosive elements.

Seaside or beachfront homeowners might wish to look for another material.

That’s because the salt in the water and air could cause the spring latch’s mechanisms to rust rashly.

In normal cases, iron lasts a long period, and it provides a great value for its price.

CHAPTER 5: All the Details about Toggle Latches: Choosing the Right Spring Latch for You

Now that you understand the different materials and how each work, there are further questions to ask which may affect your shopping decision.

If you are searching for products which provide an added layer of reliability which serves a special purpose, there are spring latches that might be a better fit for you.

How to Choose the Right Spring Latch for You?

Toggle latches offer an elegant solution to equipment accessibility.

In case you didn’t know yet:

The wide array of such products denotes that there’s one to fit most applications.

It varies from high strength units capable of enduring approximately 7,000 kg force.

It can be through discreet draw latches utilized on machinery and equipment.

Isn’t that astonishing?

The core principle behind a toggle latch is that of calibrated cam action.

It guarantees once the latch is closed, it is locked in position too.

A specific force should be exerted to overcome the cam though.

The operation is simple, thanks to the leverage given by the handle.

It’s the length of which that identifies the needed force.

A few different terms are utilized to describe a spring toggle latch. It includes:

  • Draw Latch
  • Quick release fasteners
  • Over center fasteners
  • Pull-Action Latch
  • Lever Latch
  • Tension Latch

All of which have a similar definition.

What are the Types of Toggle Latch?

Apart from spring toggle latch, there is a different range of latches.

This range guarantees that there is a model to fit most applications. These are:

  • Flush Fitting Latch – Utilized in panels where a smooth finish is needed.
  • Under center Latch – It’s a light-duty latch along with a reversed handle.

Often, it’s called as draw latch.

  • FlexibleFastener – Integrates extensible nylon and rubber components, which do the same function as the spring.
  • Adjustable Fastener – The position of the claw could be adjusted. It can be done through a rod to get the needed tension.
  • Spring Latch – The claw is made from curved spring steel. It expands as the latch is closed. An option is a mechanism or claws integrating coil springs.
  • Rigid Claw – It’s a non-adjustable latch along with a rigid claw. It’s recommended to use a rubber seal to offer some resilience.

Maximum Load Values of Spring Latches

Items are accessible in a wide array of configuration to meet the needs of the customers.

Whether  you are particular about sleek design, durability, customization or flexibility, you’ll find the right latching solution for you.

What’s more:

Spring toggle latches are categorized into different groups.

That’s to help our customers to get the right product.

When choosing a spring toggle latch, you need to determine the maximum load first.

You see:

Every latch is made for a maximum load.

No wonder:

It’s recommended to utilize a safe working load which is half its tensile strength.

The strength of the catch plate must equal to that of the spring latch.

Normally, there are four categories of spring toggle latches:

  • Light Duty – Its ultimate tensile strength differs between 11 kilograms and 90 kilograms.
  • Medium Duty – It’s made for the application needed, an ultimate tensile strength between 125 kilograms and 750 kilograms.
  • Heavy Duty – It utilizes spring latches with a UTS between 1,000 kilogram and 2,500 kilogram.
  • Super Heavy Duty – With an ultimate tensile strength of 7,000 kilograms.

If needed, further locking features can be identified.


Such might be to avoid tampering, theft, or because the installation is subject to extreme vibration.

That could lead the spring latch to open.

Thus, added locking features consists of:

  • Keylock – A discreet keylock integrated inside the spring latch.
  • Padlock – For additional security, a padlock does the similar function as a sealing pin.
  • Sealing Pin – It’s a spring-loaded pin which avoids the catch opening.
  • Safety Catch – The fastener can’t be opened unless the safety catch is free.

After understanding the ins and outs of spring toggle latches, what’s next?

Different Series of Latches

This time, we’ll discuss the different series of spring latches that are available today:

Locking Angle of Draw Latch

In a standard scenario where the point attachment is in line with the base of the spring latch, all the standard draw latches can be utilized.

Remember that the locking angle is at least 15 degrees.

On the other hand:

In a scenario where the point of attachment is past the mounting surface, several pressures might be lost.

But, how can that happen?

It may be because of the excessive over the center movement.


When a straight wire link is utilized, the connection might be slack.

Now, perhaps you’re asking yourself:

“How can I lessen such possibilities?”

To answer your question:

The attachment hole could be pierced on the center line of the pivoting hole.

The result?

It will lead to a decrease in the over the center movement.

But, wait – we don’t stop there.

Do you experience a scenario where the point of attachment is beyond the mounting surface?

Well, the two angle spring latches could be utilized in this case.

Such spring latches could be formed at their base to the appropriate angle.

You can reach the point of attachment.

Thus, keeping the proper locking angle.

Fair enough, right?
