A Carriage Bolt (DIN 603) is a round-headed bolt with a square neck beneath the head, designed to prevent rotation during installation. The smooth, domed head provides a clean and safe finish, making it ideal for applications where protruding edges are undesirable.

Carriage bolts are widely used in wood-to-wood and wood-to-metal fastening, offering strong grip and reliable performance. The square neck locks into the material, eliminating the need for a tool on the bolt head side and ensuring secure tightening from the nut end.

Manufactured as per DIN 603 standards, these bolts deliver consistent quality, durability, and excellent load-bearing capacity for both light-duty and heavy-duty assemblies.
