Professional Applications & Engineering Value
This 18-8 stainless steel socket head cap screw with nylon patch thread locker addresses critical vibration-induced loosening challenges in industrial equipment, machinery, and automotive assemblies. The UNC coarse thread design ensures rapid installation and reliable performance in high-stress applications where thermal cycling and dynamic loads are common. Engineered with Class 3A thread fit precision, this fastener maintains clamping force integrity while the partially threaded configuration provides optimal stress distribution. The combination of 70,000 psi tensile strength and chemical-resistant 18-8 stainless steel makes it ideal for corrosive environments, manufacturing equipment, and precision assemblies requiring repeated disassembly and reassembly cycles without performance degradation.
Specification Summary & Compliance
This socket head cap screw features Class 3A thread fit with UNC coarse threads (1/4"-20) and meets ASME B18.3 manufacturing specifications. The fastener is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental responsibility and regulatory adherence. With precise dimensional control including 2" length, 3/8" head diameter, and 1/4" head height, this screw delivers consistent performance across industrial applications while maintaining compliance with international standards.
