- Reliable chemical compliance meeting RoHS 3 and REACH environmental regulations for industrial safety
- Optimized for confined spaces with compact socket head design requiring only 3/32" drive tool access
Professional Applications & Engineering Value
This 316 stainless steel socket head cap screw delivers critical performance advantages in demanding industrial applications where corrosion resistance and mechanical strength are paramount. The combination of UNC coarse threads with Class 3A fit provides superior vibration resistance in machinery, automotive, and marine equipment, while the passivated finish significantly enhances pitting resistance in chemical processing and saltwater environments. The fully threaded design ensures maximum engagement in tapped holes, making it ideal for high-stress assemblies in aerospace components, precision instruments, and heavy equipment where 70,000 psi tensile strength prevents joint failure under extreme loads. The hex socket drive accommodates high torque applications while maintaining a low-profile installation in space-constrained designs.
Specification Summary & Compliance
This socket head cap screw features precision 4-40 UNC coarse threads with Class 3A fit tolerance, manufactured from 316 stainless steel with passivated finish. The fastener meets Rockwell B70 hardness specifications and delivers 70,000 psi tensile strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications requiring chemical safety compliance.
