Professional Applications & Engineering Value

This black oxide steel Phillips pan head screw delivers critical engineering advantages for industrial assembly applications where corrosion resistance and high tensile strength are paramount. The combination of 10-32 UNC fine threading with Class 2A thread fit ensures precise engagement in machinery, electronic enclosures, and automotive components, reducing the risk of cross-threading and thread stripping. The fully threaded design provides consistent clamping force across the entire 2½" length, while the rounded pan head profile offers both aesthetic appeal and practical bearing surface. These industrial screws effectively address common challenges including vibration loosening, environmental exposure, and the need for reliable, repeatable fastening in production environments.

Specification Summary & Compliance

Manufactured to exacting ASME B18.6.3 standards, this screw maintains precise dimensional accuracy with Class 2A thread fit tolerance for consistent performance. The UNC thread form with fine spacing (10-32) ensures compatibility with standard components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility, while the material specifications including 60,000 psi tensile strength and Rockwell B70 hardness guarantee mechanical reliability in demanding applications.
