Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Grade 8 hex head screws deliver critical performance where structural integrity matters most. The zinc-plated steel construction provides essential corrosion protection for machinery, structural steel connections, and outdoor equipment. The serrated locking flange eliminates the need for separate washers while providing vibration-resistant fastening in automotive assemblies and construction equipment. With 150,000 psi tensile strength and Rockwell C33 hardness, these fully threaded UNC coarse thread fasteners maintain clamp force under extreme loads, making them ideal for high-stress points in manufacturing fixtures, transportation equipment, and infrastructure projects where failure is not an option.
Specification Summary & Compliance
This 1/2"-13 UNC coarse thread fastener maintains Class 3A thread fit precision with complete threading along its 1" length. Manufacturing complies with IFI 111 and SAE J429 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) requirements for chemical safety, ensuring global regulatory acceptance for industrial distribution and use.
