Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 18-8 stainless steel hex head screws combine corrosion resistance with 80,000 psi tensile strength to solve critical fastening challenges. The UNC coarse threads and Class 2A thread fit provide reliable engagement in metals, plastics, and composites, reducing cross-threading risks. With a partially threaded shank, they excel in machinery assembly, structural frameworks, and equipment manufacturing where vibration damping and precise clamping are essential. The external hex drive ensures compatibility with standard wrenches, streamlining maintenance in tight spaces while maintaining consistent performance under cyclic loading.
Specification Summary & Compliance
This 5/16"-18 UNC hex head screw features precise Class 2A thread fit per ANSI/ASME B1.1 standards, with a coarse thread spacing for optimal grip. Manufacturing adheres to strict dimensional tolerances, including a minimum thread length of 7/8" and full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The Rockwell B70 hardness and material certification guarantee consistent mechanical properties for industrial use.
