Professional Applications & Engineering Value
This 316 stainless steel hex head screw addresses critical challenges in corrosive and high-stress environments through its marine-grade composition and UNC coarse thread design. The fully threaded configuration ensures maximum engagement in materials prone to vibration loosening, while the external hex drive accommodates high installation torque without cam-out. Engineers specify this Class 2A thread fit fastener for structural assemblies, marine hardware, and chemical processing equipment where corrosion resistance and 70,000 psi tensile strength prevent premature failure. The coarse thread spacing provides rapid installation in production environments while maintaining reliable performance under dynamic loads.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 dimensional standards with Class 2A thread tolerances for consistent fit. Features 1/4"-20 UNC coarse threads with right-hand direction and 1" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for restricted substance control. Meets industry standards for 316 stainless steel composition with Rockwell B70 hardness and 70,000 psi tensile strength verification.
