Professional Applications & Engineering Value
These 10-32 UNF flat head screws deliver critical engineering solutions where surface-flush fastening and high-strength retention are paramount. The zinc-plated steel construction provides essential corrosion protection for machinery, electrical enclosures, and automotive assemblies exposed to harsh conditions. The fine UNF threading and Class 2A fit ensure precise engagement in tapped holes, minimizing loosening from vibration - a common failure point in industrial equipment. With Rockwell B70 hardness and 60,000 psi tensile strength, these Phillips drive screws maintain structural integrity under dynamic loads while the standardized 82° countersink enables clean, professional installations in precision metalwork and manufacturing applications.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 standards with Class 2A thread fit tolerance for consistent performance. Features UNF fine threads (10-32) with right-hand direction and full threading along the 7/8" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The standard flat head profile with 82° countersink angle meets industry specifications for flush-mounted applications.
