Professional Applications & Engineering Value

This heavy-duty 1"-8 UNC hex head screw is engineered to solve critical fastening challenges in structural, machinery, and construction applications. The 18-8 Stainless Steel material provides excellent resistance to rust and oxidation, extending service life in outdoor or corrosive settings. Its coarse thread and partial threading design minimize cross-threading risks and concentrate clamping force, which is vital for securing heavy components without stripping. The external hex drive and substantial head size enable quick, high-torque installations, reducing labor time while maintaining 80,000 psi tensile strength to handle dynamic loads and vibrations. Ideal for industrial assembly, infrastructure projects, and OEM equipment, this screw delivers reliability where failure is not an option.

Specification Summary & Compliance

This screw adheres to precise dimensional standards, including a Class 2A thread fit for consistent engagement and UNC coarse threading (1"-8) per inch system requirements. It is manufactured in compliance with ASME B18.2.1 for hex head bolts and meets regulatory mandates such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free of hazardous substances and safe for industrial and international use.
