Professional Applications & Engineering Value

Engineered for industrial machinery, automotive assemblies, and precision equipment, this 1/4-20 UNC Socket Head Cap Screw addresses critical challenges like vibration-induced failure and corrosion. The 18-8 stainless steel material, combined with a Rockwell B83 hardness, resists wear and chemical exposure, while the coarse thread and Class 3A fit ensure quick, reliable engagement in high-stress environments. The flanged, partially threaded design concentrates clamping force where needed, reducing the risk of material damage and improving overall structural stability in right-hand thread applications.

Specification Summary & Compliance

This screw adheres to UNC thread standards with a Class 3A thread fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufactured to consistent inch system measurements, it guarantees reliable performance in regulated industrial settings.
