Professional Applications & Engineering Value
This Grade 5 zinc-plated steel hex head screw delivers critical performance advantages for industrial assembly and heavy equipment applications. The combination of 110,000 PSI tensile strength and Rockwell C22 hardness ensures reliable fastening in structural components, machinery frames, and automotive assemblies where vibration resistance is paramount. The UNC coarse thread design provides rapid installation in production environments while maintaining superior pull-out resistance. The integrated serrated flange eliminates the need for separate washers and prevents loosening under dynamic loads, making it ideal for construction equipment, agricultural machinery, and industrial platforms where safety and durability are non-negotiable.
