Product Details

This product is a DIN912 standard 8.8 grade high-strength hex socket head cap screw, featuring a classic cylindrical head design. It is a specialized fastener for mechanical assembly, steel structure secondary component connections, and equipment base fixing. Made from high-quality carbon steel through multiple processes including cold heading, tempering heat treatment, precision thread rolling, surface treatment, and dimensional inspection, it strictly adheres to German standard production standards. The internal hex socket groove dimensions are precise, the threads are burr-free and stripp-free, and the head and screw are firmly connected without cracks. It distributes force evenly and has a stable torque coefficient during tightening, effectively preventing loosening. Suitable for the fastening needs of various precision machinery, steel structure secondary beams, steel supports, and equipment frames, it combines high strength with aesthetically pleasing installation, making it the preferred fastener for industrial fastening and steel structure applications.
