- Standard Phillips No. 2 drive enables efficient installation with common industrial tools
- Comprehensive regulatory compliance meets ASME B18.6.3, RoHS 3, and REACH standards for global acceptance
Professional Applications & Engineering Value
These 10-32 UNF zinc-plated steel rounded head screws deliver exceptional engineering value across industrial applications where corrosion resistance and high tensile strength are critical. The fine UNF thread pattern combined with Class 2A thread fit ensures precise engagement in machinery, electrical enclosures, and structural assemblies where vibration resistance is paramount. The pan head design with Phillips drive provides a low-profile fastening solution that distributes clamping force effectively while remaining accessible for maintenance. The zinc plating creates a protective barrier against moisture and chemicals, making these partially threaded screws ideal for outdoor equipment, manufacturing fixtures, and automotive applications where environmental durability is essential.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 specifications, these screws feature Class 2A thread fit tolerances for precision assembly. The 10-32 UNF fine thread configuration with right-hand threading and partial threading over 1½" minimum thread length ensures optimal performance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and global market acceptance for industrial procurement.
