- Right-hand threading provides standard installation compatibility across industrial equipment
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Grade 8 hex head screws address critical challenges in machinery assembly, structural frameworks, and high-vibration environments. The UNF fine thread spacing combined with Class 2A thread fit creates superior resistance to loosening under dynamic loads, while the zinc yellow-chromate plating provides essential corrosion protection in manufacturing facilities and outdoor installations. The fully threaded 1½" length ensures maximum material engagement in thick assemblies, and the external hex drive accommodates high-torque installation requirements. These high tensile strength screws deliver reliable performance in automotive, construction, and industrial equipment where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 and SAE J429 specifications with Class 2A thread fit precision. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. Features 10-32 UNF fine threading with right-hand direction and fully threaded 1½" length. Grade 8 certification ensures consistent 150,000 psi tensile strength and Rockwell C33 hardness across production batches.
