Carriage bolts feature a unique design with a squared shank that remains within the hole, preventing rotation and ensuring a secure fastening. These bolts include a cylindrical head with a square or hexagonal recess, intended to be driven by a wrench or socket. DIN 603 carriage bolts meet the stringent standards set by the German Institute for Stan
This specification, EN 14399:2005, defines the requirements for high-strength structural bolted assemblies. It addresses a broad range of bolted joints used in engineering applications. The standard provides guidelines for the design, fabrication, inspection, and testing of bolted assemblies to ensure their performance. It also specifies the compon
DIN 931 outlines the standards for hexagonal head fasteners. These fixings are commonly used in numerous fields, from structural engineering tomanufacturing. The DIN 931 standard covers sizes such as diameter and thread pitch. It also sets requirements for material composition and precision. Complying with DIN 931 ensures durable connections and
