Galvanized Coarse Hex Bolt
The galvanized hex head bolt is a mechanical fastener with a hexagonal head and full threads, used for secure connections in metal and industrial structures. Diameter typically ranges from M6 to M36, with lengths from 20 to 200 mm. Made from carbon steel with heat treatment or stainless steel A2/A4, tensile strength ranges from 400–900 MPa. Galvanized surface coating provides high resistance to corrosion, moisture, and harsh environmental conditions.
Threads are manufactured according to ISO or DIN standards, ensuring uniform and strong connections with nuts. The hex head, with standard height, allows fast installation with manual or power wrenches. Galvanized hex bolts are commonly used in bridges, foundations, metal structures, and industrial equipment. Mechanical design and protective coating extend service life, reduce maintenance, and ensure connection safety.
