Professional Applications & Engineering Value

This 10-32 UNF oval head Phillips machine screw delivers critical performance advantages for industrial assembly applications where corrosion resistance and mechanical reliability are paramount. The passivated 18-8 stainless steel construction provides exceptional protection against oxidation and chemical exposure, making it ideal for marine, food processing, and outdoor equipment applications. The fine thread spacing and Class 2A thread fit ensure precise engagement with mating components, reducing the risk of loosening under vibration while the oval head profile offers a finished appearance with improved countersinking capability. With full threading along its 1-3/4" length, this fastener provides maximum thread contact for superior clamping force in demanding mechanical assemblies.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 standards with Class 2A thread fit tolerances for consistent dimensional accuracy. The UNF (Unified National Fine) thread form with right-hand direction ensures compatibility with standard components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations confirms adherence to international substance restriction requirements. The 82° countersink angle and standard oval head profile maintain proper seating in prepared surfaces.
