Professional Applications & Engineering Value

This 10-32 UNF flat head screw delivers critical engineering solutions where surface flushness and high tensile strength are paramount. The cadmium-plated steel construction provides essential corrosion protection for industrial equipment, aerospace assemblies, and machinery subjected to environmental exposure. The fine UNF threading and Class 2A thread fit ensure precise engagement in tapped holes, minimizing the risk of cross-threading while maintaining consistent clamping force. The 82° countersink angle allows the flat head to sit perfectly flush with surfaces, eliminating protrusions in applications where aerodynamics or smooth surfaces are critical. These fully threaded fasteners are particularly valuable in electronic enclosures, precision instruments, and structural components requiring reliable 60,000 psi tensile strength performance.

Specification Summary & Compliance

Manufactured to exact inch system dimensions with Class 2A thread fit tolerances per UNF standards. The screw features right-hand 10-32 UNF fine threading with 0.19" thread diameter and complies with MS35191-272 (NASM35191) military specifications. The cadmium plating meets industry standards for corrosion protection while the 82° countersink angle ensures proper seating in standard countersunk holes. This product conforms to relevant industrial fastening standards and specifications for consistent performance in professional applications.
