Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 18-8 stainless steel hex head screw combines material excellence with precision manufacturing. The 1/2"-20 UNF fine threading provides superior resistance to vibration loosening in machinery, automotive, and structural assemblies. With 80,000 psi tensile strength and Rockwell B70 hardness, it maintains integrity under repeated stress cycles. The external hex drive enables efficient installation in confined spaces, while the partially threaded design concentrates clamping force precisely where needed. These corrosion resistant fasteners deliver long-term reliability in challenging environments where chemical exposure or moisture is present.

Specification Summary & Compliance

This 3 3/4" length hex head screw features Class 2A thread fit per UNF standards with 1/2"-20 fine threading and right-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The partially threaded configuration provides minimum 1 1/4" thread length with controlled tolerance for consistent performance across industrial applications.
