Professional Applications & Engineering Value
This 18-8 stainless steel socket head cap screw is engineered to solve critical fastening challenges in industrial settings. The combination of Class 3A UNC coarse threads and integrated split lock washer provides superior vibration resistance, preventing joint failure in machinery, automotive assemblies, and heavy equipment. The fully threaded design ensures consistent clamping force along the entire 1" length, while the 3/16" hex drive allows for high-torque installation in confined spaces. Manufactured from corrosion-resistant 18-8 stainless steel, this fastener maintains integrity in moist or chemical-exposed environments, reducing maintenance costs and downtime. Its 70,000 psi tensile strength makes it ideal for high-stress applications where reliability is paramount.
Specification Summary & Compliance
This socket head cap screw features precision 1/4"-20 UNC Class 3A threads with coarse spacing and right-hand direction. The fastener is fully threaded and meets ASTM F837 manufacturing specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The integrated split lock washer, made from 18-8 stainless steel, complements the screw's high-performance specifications.
