Professional Applications & Engineering Value
These Grade 5 zinc-plated steel hex head screws deliver critical performance advantages in demanding industrial settings. The combination of 110,000 psi tensile strength and Rockwell C22 hardness provides exceptional resistance to shear and tensile forces, making them ideal for structural assemblies, heavy machinery, and automotive applications. The UNF fine thread configuration offers superior vibration resistance compared to coarse threads, while the external hex drive enables high-torque installation with standard tools. The integrated serrations beneath the flange create a positive locking action that prevents loosening in dynamic load conditions, eliminating the need for additional locking components. These fully threaded fasteners ensure maximum grip length and uniform stress distribution across the entire engagement area.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with 5/16"-24 UNF fine threads and right-hand orientation. Complies with IFI 111 specifications where identified as SAE J429 for Grade 5 mechanical properties. Meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) environmental standards. Features include 1 1/2" length, 11/16" flange diameter, and fully threaded construction with external hex drive configuration.
