• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for heavy-duty load-bearing applications
• Reliable coarse UNC threading provides faster installation and better performance in softer materials or where debris is present
• Secure external hex drive design with 1 7/8" head width for high-torque tightening and easy installation with standard tools
• Optimized partial threading on a 7 1/2" length allows for precise clamping force distribution in thick materials
• Precision Class 2A thread fit ensures consistent engagement and reliable performance in industrial assemblies
• Full regulatory compliance with ASME B18.2.1 manufacturing standards plus RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

This 1 1/4"-7 UNC hex head screw in 316 stainless steel delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The coarse UNC thread design prevents cross-threading and enables rapid assembly in structural steel, heavy machinery, and marine equipment. With its partially threaded configuration and 7 1/2" length, it provides optimal shear strength while minimizing thread damage in high-vibration environments. The external hex drive and substantial 1 7/8" head width allow for maximum torque application without stripping, making it ideal for critical connections in chemical processing plants, offshore platforms, and industrial infrastructure where failure is not an option.

Specification Summary & Compliance

This hex head screw features precision UNC coarse threads with Class 2A thread fit tolerance, ensuring consistent mating with standard nuts and threaded components. Manufacturing strictly follows ASME B18.2.1 specifications for dimensional accuracy and mechanical properties. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial applications with strict environmental and safety requirements.
