Professional Applications & Engineering Value
This Grade 5 hex head screw delivers critical reliability for industrial applications where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection in manufacturing, machinery, and outdoor equipment assemblies. Its serrated locking flange eliminates the need for separate washers while creating permanent bite into mating surfaces, solving common loosening issues in dynamic load conditions. The combination of UNC coarse threading with Class 2A fit ensures rapid installation in both soft and hard materials, reducing assembly time while maintaining 110,000 psi tensile strength for heavy-duty fastening requirements across automotive, construction, and industrial maintenance sectors.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC thread form (1/4"-20) with coarse spacing. Fully compliant with IFI 111/SAE J429 specifications for Grade 5 fasteners, along with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features include 1/2" length, 9/16" flange diameter, external hex drive, and right-hand threading for standardized industrial applications.
