Professional Applications & Engineering Value

This heavy-duty hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 18-8 Stainless Steel composition withstands corrosive environments in marine, chemical processing, and outdoor construction applications. The coarse UNC thread pattern with Class 2A thread fit provides excellent engagement in both metallic and non-metallic substrates, reducing cross-threading risks during high-volume assembly operations. The partially threaded design concentrates tensile strength where needed most while minimizing material costs. With 80,000 psi tensile strength and external hex drive compatibility, this fastener meets rigorous demands in structural steelwork, heavy machinery, and infrastructure projects where vibration resistance and long-term reliability are essential.

Specification Summary & Compliance

This 1 1/4"-7 UNC hex head screw maintains precise Class 2A thread tolerances according to Unified Thread Standard specifications. The manufacturing process ensures consistent thread diameter of 1.25" with coarse thread spacing for optimal performance. The product fully complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. Mechanical properties including Rockwell B70 hardness and 80,000 psi tensile strength meet industrial requirements for high-strength fastening applications.
