Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel socket head cap screws deliver critical corrosion resistance where exposure to chemicals, moisture, or extreme temperatures would compromise ordinary fasteners. The cold worked fabrication process enhances grain structure, providing exceptional 110,000 psi tensile strength that prevents failure under heavy loads and vibration. With Class 3A thread fit and UNC coarse threading, these fasteners ensure precise engagement in machinery, automotive assemblies, and marine equipment where reliability is paramount. The hex socket drive design allows for high torque application in confined spaces, making them ideal for precision equipment maintenance and manufacturing applications requiring frequent disassembly.
Specification Summary & Compliance
This 1/4"-20 UNC socket head cap screw features Class 3A thread fit precision with right-hand direction and fully threaded design. Manufactured to ASME B18.3 specifications with dimensional accuracy including 1" length, 3/8" head diameter, and 1/4" head height. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for restricted substance control.
