• Precision Class 3A thread fit provides tighter tolerances for secure, vibration-resistant fastening
• 1/4" hex drive design allows for easy installation and removal with standard tools in confined spaces
• Partially threaded coarse UNC thread enables faster assembly and better grip in various materials
• Rockwell B70 hardness maintains structural integrity and durability under repeated use
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and global market acceptance

Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw delivers exceptional performance in demanding applications where corrosion resistance and mechanical strength are critical. The passivated finish enhances durability in chemical-rich or marine environments, while the UNC coarse thread and Class 3A fit prevent loosening under dynamic loads. Engineered with a 1/4" hex drive, it facilitates secure fastening in machinery, automotive assemblies, and structural frameworks where access is limited. Its 70,000 psi tensile strength and Rockwell B70 hardness ensure long-term reliability in high-stress industrial settings, reducing maintenance frequency and downtime.

Specification Summary & Compliance

This socket head cap screw adheres to Class 3A thread fit standards with UNC coarse threading (5/16"-18) and a minimum thread length of 1 1/8". Manufactured to precise dimensional tolerances in the inch system, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety and regulatory acceptance for industrial fastener applications.
