Carriage bolt

Carriage Bolts are specially designed fasteners featuring a smooth rounded head and square neck beneath the head for secure and slip-resistant fastening. These bolts are widely used in wood-to-wood, wood-to-metal, and structural applications where a clean and finished appearance is required. Manufactured with precision threading and high-quality materials, carriage bolts provide excellent strength, durability, and corrosion resistance for long-lasting performance.

Carriage Bolt Specifications for Project Enquiries

Carriage bolts, also called cup-head square-neck bolts, have a rounded head and a square neck intended to resist rotation in a suitably prepared joint. They are used in timber-to-timber and timber-to-metal connections, fabrication, fencing, joinery and other engineered fastening assemblies. Bolt selection must follow the relevant joint design.

When requesting carriage bolts in Dubai or elsewhere in the UAE, specify nominal diameter, under-head length, thread length, mating nut and washer requirements, material or grade, finish, quantity and any applicable drawing or standard. The product information lists M6–M24 diameters and 25–300 mm lengths as reference ranges; confirm individual combinations and availability with the supplier. If a DIN 603-type cup-head square-neck bolt is required, identify it on the enquiry rather than assuming standards compliance.
