Shoot Bolts vs Tower Bolts: What’s the Difference and Which Do You Need?

When you are buying hardware for a gate, door, shutter, trailer, steel frame, or industrial product, you may see two similar names: shoot bolts and tower bolts.

At first, they may look like the same thing. Both are sliding bolts. Both are used to keep something closed. Both can be fitted to doors and gates. But they are not always the same.

The simple answer is:

A tower bolt is usually a basic sliding bolt used on doors, gates, sheds, and shutters. A shoot bolt is a wider term used for many types of sliding bolts, including heavier industrial bolts, spring bolts, gate bolts, and locking plungers.

So, a tower bolt can be seen as one type of sliding bolt, but a shoot bolt is a broader product category. In this guide, we will explain the difference in simple words. We will also help you understand which one is better for your job.

What Is a Shoot Bolt?

A shoot bolt is a metal bolt that slides into a hole, keep, frame, receiver, or bracket to hold something in place.

It works in a very simple way. You move the bolt forward, and it locks or holds the door, gate, panel, or frame. When you pull it back, the item can open or move again.

Shoot bolts are often used on:

  • Gates
  • Steel doors
  • Trailers
  • Pallet frames
  • Warehouse equipment
  • Metal panels
  • Machine guards
  • Agricultural gates
  • Fabricated steel products
  • Industrial access doors

Shoot bolts can be small and simple, or they can be heavy-duty and made for strong industrial use. Read in more detail about shoot bolts in this detailed guide. 

What Is a Tower Bolt?

A tower bolt is also a sliding bolt, but it is usually a more specific type.

Tower bolts are very common on domestic and light commercial doors. You may have seen them on:

  • Garden gates
  • Shed doors
  • Bathroom doors
  • Cupboard doors
  • Shutters
  • Wooden doors
  • Small metal gates
  • Storage rooms

A tower bolt is normally fitted on the surface of a door or gate. It has a sliding bar and a small handle or knob. You slide the bar into a keep or socket to hold the door closed.

Tower bolts are popular because they are simple, cheap, and easy to fit.

How Does a Tower Bolt Work?

A tower bolt works by sliding a metal bar into a matching keeper.

For example, if it is fitted on a gate, you slide the bolt into a bracket on the gate post. This keeps the gate closed. If it is fitted on a door, the bolt may slide into the door frame, floor, or another fixed part.

Most tower bolts are manually operated. This means you move them by hand. They usually do not have springs or special locking mechanisms, although some stronger or lockable versions are available.

Main Difference Between Shoot Bolts and Tower Bolts

The main difference is the range of use.

A tower bolt is normally a simple sliding bolt for a door or gate. It is easy to fit and easy to use.

A shoot bolt can do the same job, but it can also do much more. It can be used in heavier, stronger, and more industrial applications.

So, if you are fitting a small shed door, a tower bolt may be enough. But if you are building a steel gate, trailer panel, pallet frame, or industrial product, a shoot bolt is usually the better choice.

For example, a small bolt on a shed door may be called a tower bolt. But a spring-loaded bolt used on a steel trailer or pallet frame would usually be called a shoot bolt, spring bolt, or plunger.

That is why product names can change depending on the industry.

  • A homeowner may search for a tower bolt.
  • A fabricator may search for a shoot bolt.
  • A gate manufacturer may search for a gate bolt.
  • An engineer may search for a locking plunger.

The product may look similar, but the design and purpose can be different.

Common Names Used for Shoot Bolts

Shoot bolts can be called by many names. Here are some common related terms:

NameSimple Meaning
Spring shootA shoot bolt with spring action
Gate boltA bolt mainly used for gates
Spring-return boltA bolt that returns back with spring force
Spring-loaded door boltA door bolt with a spring mechanism
Barrel bolt (spring type)A round sliding bolt with spring action
Latch boltA bolt used for latching or holding something closed
Locking indexing plungerA spring-loaded plunger used for locating, locking, or positioning parts

These names are sometimes used in different ways by different suppliers. The important thing is to look at the product design, size, material, and action before buying.

Where Are Shoot Bolts Used?

Shoot bolts are used in many industries because they are simple and strong.

They are especially useful when a door, gate, panel, or frame needs to stay in a fixed position.

1. Gates and Fencing

Shoot bolts are commonly used on metal gates, farm gates, industrial gates, and security gates.

They can be used to hold the gate closed. They can also be used to hold one side of a double gate in place while the other side opens.

For larger gates, a stronger shoot bolt is usually better than a small tower bolt. This is because large gates can move in the wind or under pressure.

2. Trailers and Transport Frames

Trailers often need strong locking hardware. A trailer ramp, side panel, or tailgate must stay closed during movement.

Shoot bolts are useful because they can lock panels into place quickly. They can also handle regular use in outdoor and transport conditions.

In this type of work, strength and reliability are very important.

3. Pallet Frames and Stillages

In industrial storage, pallet frames and stillages often have moving sides, gates, or panels.

Shoot bolts can help keep these parts closed during storage, handling, or transport.

A strong bolt helps stop the frame from opening by accident. This can make handling safer and easier.

4. Machinery Guards

Many machines have guards or access panels. These panels need to stay closed when the machine is in use.

Shoot bolts can help hold these guards in position.

For machinery, it is important to choose the correct bolt. The bolt must be strong enough and suitable for the safety requirements of the equipment.

5. Agricultural Equipment

Farm gates, animal pens, trailers, and agricultural equipment often use shoot bolts.

These products are usually used outside, so the hardware must handle weather, dirt, and repeated use.

A zinc-plated or galvanised finish can help improve corrosion resistance.

6. Steel Fabrication

Fabricators use shoot bolts in many custom steel products. They may weld the bolt onto a frame or design a bracket around it. This makes shoot bolts useful for custom gates, cages, access panels, trolleys, stillages, and storage systems.

For fabrication, shoot bolts are often more suitable than standard tower bolts because they offer more fitting options.

Where Are Tower Bolts Used?

Tower bolts are usually used in simpler applications.

They are common in homes, shops, gardens, and light commercial buildings.

1. Shed Doors

A tower bolt is a simple way to hold a shed door closed. It is easy to fit and easy to operate.

For extra security, some people use a tower bolt together with a padlock or hasp and staple.

2. Garden Gates

Tower bolts are often fitted to small wooden or metal garden gates.

They can help keep the gate closed when it is not in use. For larger or heavier gates, a stronger gate bolt or shoot bolt may be better.

3. Cupboards and Storage Rooms

Small tower bolts are also used on cupboards, storage rooms, and internal doors.

In these cases, the bolt does not need to handle heavy force. It only needs to keep the door closed.

4. Shutters

Tower bolts can be fitted to shutters to stop them from opening.

For light shutters, a tower bolt may be enough. For larger shutters or industrial shutters, a stronger bolt may be needed.

Which One Is Stronger?

A shoot bolt is not always stronger than a tower bolt, but shoot bolts are often available in stronger and more industrial designs.  A small shoot bolt may be weaker than a heavy tower bolt. A heavy-duty shoot bolt may be much stronger than a small tower bolt.

So, strength depends on:

  • Material
  • Diameter of the bolt
  • Length of the bolt
  • Thickness of the body
  • Fixing method
  • Finish
  • Quality of manufacture
  • How it is fitted

For heavy-duty use, do not only look at the product name. Look at the full specification.

A strong bolt fitted badly can still fail. A good fixing method is just as important as the bolt itself.

Which One Is Easier to Fit?

A tower bolt is usually easier to fit.

Most tower bolts are surface-mounted. You place the bolt on the door or gate, mark the holes, drill pilot holes if needed, and screw it into place.

Shoot bolts can also be easy to fit, but some types need more planning. For example, weld-on shoot bolts need welding. Some industrial bolts need brackets or accurate positioning.

So, for a simple DIY job, a tower bolt is often easier. For fabrication or industrial use, a shoot bolt is usually more suitable, even if fitting takes more time.

Which One Is Better for Security?

Both shoot bolts and tower bolts can improve security, but they are not always full security locks by themselves.

A simple tower bolt can stop a door or gate from opening, but it may not stop forced entry if the door is weak or the screws are exposed.

A shoot bolt can be stronger, especially when used with a strong frame and proper receiver. Some shoot bolts can also be padlocked or designed with a locking feature.

For better security, think about the full system:

  • Is the door or gate strong?
  • Is the frame strong?
  • Are the fixings strong?
  • Can the bolt be accessed from outside?
  • Can the screws be removed?
  • Is a lock needed?
  • Is the receiver strong enough?

The bolt is only one part of the security setup.

Things to Check Before Choosing

Before you buy a shoot bolt or tower bolt, ask yourself a few simple questions.

1. What Are You Securing?

Are you securing a small cupboard, a garden gate, a steel gate, a trailer ramp, or an industrial frame?

For small indoor jobs, a tower bolt may be fine. For heavier outdoor or industrial jobs, a shoot bolt may be better.

2. How Heavy Is the Door or Gate?

The heavier the door or gate, the stronger the bolt should be.

A large steel gate can put more pressure on the bolt than a small wooden cupboard door.

3. Is It for Indoor or Outdoor Use?

Outdoor hardware needs to handle rain, moisture, and changing weather.

For outdoor use, choose a suitable finish such as zinc-plated, galvanised, or stainless steel.

4. Do You Need Spring Action?

Some jobs need the bolt to return by itself. Other jobs only need a manual sliding action.

If the bolt is used many times a day, a spring action may make it easier and faster to use.

5. Do You Need Locking?

Some bolts simply hold a door closed. Others need to be locked for extra security.

If security is important, choose a lockable design or use the bolt with another locking system.

6. How Will It Be Fitted?

Will it be screwed, bolted, or welded?

Tower bolts are usually screwed on. Shoot bolts may be screwed, bolted, or welded depending on the design.

When Should You Choose a Shoot Bolt?

Choose a shoot bolt if you need a stronger or more industrial solution.

A shoot bolt is usually the better choice for:

  • Steel gates
  • Fabricated products
  • Industrial doors
  • Trailers
  • Pallet frames
  • Stillages
  • Warehouse equipment
  • Agricultural gates
  • Machinery guards
  • Heavy-duty panels
  • Repeated-use applications

Shoot bolts are also better when you need more choice in design. For example, you may need a spring action, a longer bolt, a stronger body, a weld-on fixing, or a locking plunger style.

If you are manufacturing or fabricating a product, shoot bolts are often easier to design into the frame.

When Should You Choose a Tower Bolt?

Choose a tower bolt if you need a simple sliding bolt for a lighter job.

A tower bolt is usually suitable for:

  • Shed doors
  • Garden gates
  • Cupboard doors
  • Internal doors
  • Small shutters
  • Storage rooms
  • Light-duty panels

Tower bolts are good when you want something simple, low-cost, and easy to fit.

They are not always the best choice for heavy industrial use. If the door or gate is large, heavy, or used often, a stronger shoot bolt may be a better option.

Conclusion

Shoot bolts and tower bolts are similar because both use a sliding action to secure something. But they are not always the same.

A tower bolt is usually a simple sliding bolt used on doors, sheds, cupboards, shutters, and light gates. It is easy to fit and works well for basic jobs.

A shoot bolt is a broader and more flexible product type. It can be used for gates, trailers, pallet frames, machinery guards, steel fabrication, and industrial equipment. It can also include spring-loaded, lockable, weld-on, and plunger-style designs.

So, which one do you need? For light domestic jobs, a tower bolt is often enough. For stronger, heavier, or industrial jobs, a shoot bolt is usually the better choice.

FAQs

What size shoot bolt should I choose for a heavy gate?

For a heavy gate, choose a longer and thicker shoot bolt with a strong body and secure fixing points. The bolt should be large enough to handle gate movement, vibration, and outdoor use without bending or becoming loose.

Which is better for a wooden door: shoot bolt or tower bolt?

For a simple wooden door, a tower bolt is often enough because it is easy to fit and operate. A shoot bolt may be better if the door is heavy, used often, or needs a stronger holding point at the top, bottom, or side.
