Professional Applications & Engineering Value
These Black Oxide 18-8 Stainless Steel socket head cap screws deliver critical performance advantages in precision engineering applications. The combination of UNC coarse threading and Class 3A fit provides exceptional vibration resistance in machinery, automotive assemblies, and electronic enclosures where loosening under dynamic loads is a concern. The corrosion-resistant coating on the 18-8 stainless steel base material ensures long-term reliability in humid or chemically aggressive environments, eliminating premature fastener failure. The hex socket drive system enables high clamping forces without stripping, while the fully threaded design allows for precise adjustment in depth-critical applications. These industrial fasteners solve common challenges of maintenance frequency, installation efficiency, and long-term structural integrity in demanding B2B applications.
Specification Summary & Compliance
This socket head cap screw features precision 4-40 UNC coarse threads with Class 3A fit for tight tolerance applications. Manufacturing specifications include a right-hand thread direction and standard socket head profile with dimensions of 0.183" head diameter and 0.112" head height. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental regulation adherence for industrial and international markets.
