Professional Applications & Engineering Value
Engineered for demanding industrial environments, this 316 stainless steel socket head cap screw delivers critical corrosion resistance where exposure to chemicals, moisture, or marine conditions would compromise ordinary fasteners. The passivated finish enhances surface durability while maintaining the material's inherent corrosion-resistant properties. Its Class 3A thread fit ensures precise tolerances for vibration-prone applications, from heavy machinery to precision equipment. The combination of 70,000 psi tensile strength and coarse UNC threads provides reliable performance in high-stress assemblies while facilitating faster installation. The 1/4" hex drive socket offers superior torque transmission compared to standard screw heads, making it ideal for confined spaces requiring high clamping forces.
Specification Summary & Compliance
This socket head cap screw features 5/16"-18 UNC coarse threads with Class 3A thread fit precision, manufactured to exacting dimensional standards. The fastener maintains Rockwell B70 hardness and 70,000 psi tensile strength throughout its 2 1/4" length with partial threading. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial applications worldwide.
