Professional Applications & Engineering Value
These Grade 8 hex head screws deliver critical performance in demanding applications where failure is not an option. The steel construction combined with 150,000 psi tensile strength makes them suitable for structural connections, heavy machinery assembly, and construction projects requiring reliable load transfer. The zinc yellow-chromate plating provides essential corrosion protection in industrial environments exposed to moisture and chemicals. With coarse UNC threading and Class 2A thread fit, these fasteners offer quick installation and vibration resistance in steel frameworks, equipment bases, and automotive components. The fully threaded design ensures maximum engagement in thick materials, distributing clamp force evenly to prevent joint failure under dynamic loads.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse thread spacing for consistent performance. Complies with ASME B18.2.1 and SAE J429 Grade 8 specifications for material and mechanical properties. Meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring safe use across various industrial sectors.
