Carriage Bolts for Secure and Clean Fixings

They are used where a smooth, tamper resistant fixing is required. They feature a round, low-profile head and a square neck beneath the head. This design prevents the bolt from turning once installed.

At Steel & Prefabs, we supply carriage bolts that are built for construction, not light DIY work. These bolts are simple, reliable, and effective when used correctly.

How Carriage Bolts Work

These bolts are installed by inserting it through a pre-drilled hole. As the nut is tightened, the square neck bites into the material. This locks the bolt in place and stops it from rotating.

This makes round head carriage bolts ideal for applications where access is only available from one side. The smooth head also reduces the risk of tampering or injury.

Why Use Carriage Bolts

 These bolts are commonly used in timber and light steel connections. They are especially useful in exposed areas where a clean finish is required.

Key advantages include:

• Smooth, low-profile head

• Anti-rotation square neck

• Easy installation with standard tools

• Secure fixing for wood and steel

• Clean appearance after installation

These features make square neck carriage bolts a practical choice for structural and non-structural applications.

Common Applications

Carriage bolts for construction are widely used in:

• Timber structures and framing

• Fencing and gates

• Steel to wood connections

• Outdoor furniture and fixtures

• Agricultural and utility buildings

For outdoor use, galvanized carriage bolts provide added protection against corrosion and weather exposure.

Supplied for Real Use

Not all bolts are the same. Poor quality bolts strip, bend, or fail under load. That leads to loose connections and repeated repairs.

As a trusted carriage bolts supplier in Kenya, Steel & Prefabs supplies bolts that meet strength and durability requirements. We provide consistent sizes, proper threading, and finishes suited to the environment.
