Professional Applications & Engineering Value
Engineered for demanding industrial applications, this 1 1/8"-7 UNC hex head screw in 316 stainless steel addresses critical challenges in corrosive environments and high-stress assemblies. The coarse thread design provides superior resistance to vibration loosening while enabling quicker installation in structural steel, heavy machinery, and marine equipment. With partial threading and substantial 5 1/2" length, it offers precise clamp load control and prevents thread galling in thick materials. The external hex drive configuration ensures maximum torque application without stripping, making it indispensable for maintenance operations and original equipment manufacturing where reliability under extreme conditions is paramount.
Specification Summary & Compliance
This heavy-duty hex screw maintains precise Class 2A thread fit per UNC standards with 1 1/8"-7 coarse threading and 2 1/2" minimum thread length. Manufacturing conforms to ASME B18.2.1 dimensional specifications, while material composition meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for hazardous substance restrictions.
