• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term durability in demanding industrial environments
• Maximum holding power from the fully threaded 3" length and fine UNF thread design, providing reliable, vibration-resistant fastening
• Efficient installation with Phillips No. 2 drive and standard pan head, allowing for secure tool engagement and consistent torque application
• Precision-engineered compatibility with recommended 11/64" drill bit, ensuring proper fit and reducing the risk of material damage or thread stripping
• Industry-standard compliance with ASME B18.6.3 and SAE J933 specifications, guaranteeing consistent quality and interchangeability
• Versatile Type F thread cutting design with blunt tip for controlled entry and reduced cross-threading in various metal substrates

Professional Applications & Engineering Value

These 10-32 UNF thread cutting tapping screws are engineered to solve critical fastening challenges in metalworking and assembly operations. The zinc-plated steel construction provides essential corrosion protection for extended service life in harsh conditions, while the Type F thread cutting design with fine UNF threads creates precise, secure mating threads in aluminum, brass, cast iron, and sheet metal without requiring pre-tapped holes. This eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The fully threaded 3" length ensures maximum thread engagement along the entire fastener, delivering superior pull-out strength and vibration resistance in demanding applications such as machinery assembly, metal fabrication, and industrial equipment maintenance. The combination of Phillips No. 2 drive and standard pan head profile facilitates efficient installation with common tools while maintaining a low-profile appearance.

Specification Summary & Compliance

These tapping screws feature 10-32 UNF fine threads with a thread diameter of 0.19" and are fully threaded along the 3" length. Manufactured to Class 2A thread tolerances with a blunt tip and round shank cross-section, they comply with ASME B18.6.3 and SAE J933 standards for dimensional accuracy and performance. The zinc-plated steel finish meets industry requirements for corrosion protection, and the Type F thread cutting design is optimized for use with an 11/64" (0.1719") drill bit size. These fasteners are suitable for creating secure threads in various metal substrates without additional tapping operations.
