Product Description

The M12x100 hex bolt is a half-thread hex bolt designed in compliance with DIN 933 standards, featuring a 12 mm nominal diameter and 100 mm overall length. The partial threading spans approximately half the shank, optimizing load distribution and grip strength. Constructed from high-grade carbon steel with a galvanized or black oxide finish, it provides corrosion resistance and a tensile strength of 8.8 grade (800 MPa minimum). Suitable for temperatures ranging from -20°C to 120°C, this bolt is widely used in machinery, automotive assembly, and structural applications. Advantages include durability, standardized DIN compatibility, and ease of installation using standard M12 nuts. A key limitation is the requirement for precise torque tools to avoid thread stripping. The hexagonal head design ensures secure wrench engagement, while the half-thread configuration balances clamping force and alignment stability in dynamic environments.
