Professional Applications & Engineering Value
This 1 1/8"-7 UNC hex head screw delivers critical performance where structural integrity matters most. The 18-8 Stainless Steel composition provides inherent corrosion resistance that withstands chemical exposure and outdoor elements, eliminating premature fastener failure. With its coarse thread pitch and Class 2A thread fit, this screw maintains secure connections in high-vibration machinery, construction equipment, and heavy structural assemblies. The partial threading concentrates clamping force precisely where needed, while the external hex drive accommodates high installation torque without stripping. Engineered for industrial applications requiring both durability and regulatory compliance, this fastener solves critical challenges in manufacturing, infrastructure, and heavy equipment maintenance.
Specification Summary & Compliance
This heavy-duty hex head screw features 1 1/8"-7 UNC coarse threads with Class 2A thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and reliable engagement. The 9-inch length with 2 3/4" minimum thread length provides optimal fastening capability. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and global market acceptance for industrial applications.
