Professional Applications & Engineering Value
These zinc-plated steel machine screws provide exceptional value in industrial assembly where corrosion resistance and mechanical strength are critical. The UNC coarse threading and Class 2A thread fit ensure rapid installation and reliable performance in metal, plastic, and composite materials, reducing assembly time while maintaining joint integrity. The Phillips pan head design offers a low-profile solution for applications where clearance is limited, while the fully threaded configuration maximizes pull-out resistance. Ideal for electrical enclosures, machinery assemblies, and automotive components, these screws deliver consistent performance across temperature variations and mechanical stress conditions.
Specification Summary & Compliance
Manufactured to precise ASME B18.6.3 standards with Class 2A thread tolerances for consistent fit and performance. Features 8-32 UNC coarse threads with standard 1/2" length and 0.322" head diameter. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors while maintaining 60,000 psi tensile strength and Rockwell B70 hardness specifications.
