Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 316 stainless steel hex head screws deliver exceptional performance where corrosion resistance and mechanical integrity are paramount. The UNC coarse thread configuration ensures rapid installation and superior holding power in structural applications, while the partial threading design optimizes stress distribution across the fastener length. With their external hex drive and right-hand thread orientation, these fasteners provide reliable service in chemical processing equipment, marine hardware, and outdoor infrastructure where exposure to moisture and corrosive elements would compromise ordinary fasteners. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes them ideal for high-stress assemblies requiring repeated maintenance access without thread degradation.

Specification Summary & Compliance

These hex head screws feature precision 1/2"-13 UNC threads with Class 2A thread fit tolerance, ensuring consistent mating with standard nuts and tapped holes. Manufacturing strictly adheres to ASME B18.2.1 dimensional standards, guaranteeing interchangeability and proper clearances. The 6" length with 1 1/4" minimum thread length provides optimal unthreaded shank for shear applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial procurement.
