stainless steel 304 allen bolt 12X70
The Allen bolt stainless steel 304 cylindrical head size M12 length 70 mm is manufactured from austenitic stainless steel grade 304, with an approximate weight of 80 to 85 grams. Its tensile strength is around 700 MPa, and the thread surfaces exhibit high wear resistance, allowing it to withstand dynamic loads and repeated fastening. The cylindrical head with an internal hex drive ensures uniform load distribution and easy assembly.
In terms of environmental resistance, the M12 length 70 stainless steel Allen bolt has a natural silver metallic color and performs very well against rust and weak acids. It endures over 500 hours in salt spray testing according to ASTM B117 and is suitable for humid industrial environments, pipelines, and marine equipment.
The thread is designed according to ISO 4762 standards, with a pitch of 1.75 mm and sufficient thread depth to ensure uniform load transfer. Its high wear resistance allows stable performance under repeated fastening and dynamic loading. These features make the bolt widely used in oil and gas, mechanical equipment, industrial machinery, and heavy steel structures.
