Black Socket Head Cap Screw DIN912
Hexagon socket head bolts feature a cylindrical head with a recessed hexagonal socket that can be easily installed using an Allen wrench or hexagonal wrench. Hexagon socket head bolts provide a secure and reliable connection and are ideal for applications requiring high strength and precision. Conformity to DIN 912 ensures consistent quality and compatibility with other DIN 912-compliant components. Whether in automotive, mechanical or construction projects, hexagon socket head bolts are the first choice for professionals looking for a strong and efficient fastening solution. Blackening is a common chemical surface treatment. The principle is to create an oxide film on the metal surface, which insulates it from air and prevents rusting. The blackening process increases the service life of the bolts and provides better rust protection than ordinary bolts.
