Carriage bolts feature a unique design with a squared shank that remains within the hole, preventing rotation and ensuring a secure fastening. These bolts comprise a cylindrical head with a square or hexagonal recess, designed to be driven by a wrench or socket. DIN 603 carriage bolts adhere to the stringent standards set by the German Institute fo
This document, EN 14399:2005, defines the requirements for high-strength structural bolted assemblies. It deals with a broad range of bolted joints used in structural applications. The standard outlines methods for the design, fabrication, inspection, and testing of bolted assemblies to ensure their reliability. It also specifies the materials that
DIN 931 defines the standards for hex head bolts. These fixings are widely employed in various fields, from structural engineering toconstruction. The DIN 931 standard covers parameters such as length and thread form. It also sets requirements for material quality and tolerances. Adhering to DIN 931 ensures reliable connections and boosts the int
