Round head guardrail bolt

The round head guardrail bolt is a specialized fastener designed for securing guard rails and barriers in place. Its unique design features a round head with a flat bearing surface and a square neck just below the head. This square neck is intended to be embedded into the material being fastened, preventing the bolt from turning when the nut is tightened. The round head provides a smooth and safe surface, reducing the risk of injury from protruding edges.

In terms of structure, the round head guard rail bolt typically consists of a threaded shank, a round head, and a square neck section. The threaded shank is designed to be inserted through pre-drilled holes in the guard rail and then secured with a nut on the opposite side. The round head allows for a safe and aesthetically pleasing finish, while the square neck prevents the bolt from rotating during installation.

These bolts are commonly used in applications where safety and aesthetics are important, such as on highways, bridges, and other public infrastructure. They are available in various materials, including steel and stainless steel, and are often hot-dip galvanized for corrosion resistance, making them suitable for outdoor use.

Guardrail Bolt Standards

The standards for highway guardrail bolts mainly include the following aspects:
Material standards: Highway guardrail bolts are mainly made of carbon structural steel, and their material standards should comply with GB/T699 and other relevant standards.

Size standards: The diameter of highway guardrail bolts should be 8mm-18mm.

Strength standards: Highway guardrail bolts should meet relevant requirements such as a minimum tensile strength of 400 MPa, a minimum yield strength of 240 MPa, and a minimum elongation rate of 22%.

Surface treatment standards: The surface of highway guardrail bolts should be anti-corrosion treated, which can be galvanized, hot-dip galvanized, etc.

Full load standard: Highway guardrail bolts should meet the size limit to withstand the maximum load.
Bolt material: The material of the high-speed guardrail plate bolts should be stainless steel or anti-corrosion treated carbon steel.

Bolt installation requirements: Bolts should be evenly stressed when fixed to achieve the expected pre-tightening force. After tightening the bolts, use a micrometer to check whether the pretightening force meets the requirements. Bolts that do not meet the standard need to be replaced.

Depth of embedded parts: The depth of embedded parts of high-speed guardrail panels should meet the design requirements.
Bolt spacing: The bolt spacing of high-speed guardrail panels should meet the design requirements.
