Professional Applications & Engineering Value
This 1 1/4"-7 UNC hex head screw delivers critical engineering solutions for industrial applications requiring corrosion-resistant fastening. The 18-8 stainless steel composition prevents rust and degradation in marine, chemical processing, and outdoor installations. With 80,000 psi tensile strength and Rockwell B70 hardness, it maintains structural integrity under extreme loads and vibrations. The coarse UNC thread pattern provides rapid installation in steel frameworks, machinery bases, and construction assemblies, while partial threading concentrates clamping force where needed most. These features combine to solve common industrial challenges including material fatigue, environmental exposure, and maintenance accessibility.
Specification Summary & Compliance
This heavy-duty fastener features Class 2A thread fit tolerance for precise engagement and meets ASME B18.2.1 manufacturing specifications. The 1 1/4"-7 UNC coarse thread configuration ensures compatibility with standard components. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence. The 6" length with 2 3/4" minimum thread length provides optimal fastening capability for industrial applications requiring robust, reliable connections.
