Professional Applications & Engineering Value

These 10-32 UNF flat head screws deliver critical engineering solutions where precision fastening meets environmental challenges. The 18-8 stainless steel core provides fundamental corrosion resistance, while the black-oxide passivated finish enhances surface durability and reduces galling during installation. The Class 3A thread fit ensures tight tolerances for vibration-prone applications in machinery, electronic enclosures, and automotive assemblies. The 82° countersink angle and flat head profile allow for flush mounting in precision equipment where surface protrusions are unacceptable. These fully threaded fasteners maintain consistent clamping force across the entire engagement length, making them ideal for industrial applications requiring reliable, high-strength connections in confined spaces.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with Class 3A thread fit precision and UNF fine threading standards. Features include 10-32 thread size, 3/8" length, and 82° countersink angle. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while maintaining 70,000 psi tensile strength and Rockwell B55 hardness specifications.
