Professional Applications & Engineering Value

These 10-24 UNC coarse thread tapping screws deliver exceptional engineering value in industrial fastening applications where material integrity and vibration resistance are critical. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for demanding environments. The thread cutting design (Type F) creates precise mating threads in aluminum, brass, cast iron, and sheet metal without requiring pre-tapped holes, significantly reducing assembly time and labor costs. The No. 2 Phillips drive ensures reliable installation with standard tools, while the fully threaded configuration maximizes surface contact for superior pull-out resistance. These tapping screws are engineered to prevent loosening under vibration and maintain clamping force in dynamic industrial applications, making them ideal for manufacturing equipment, metal fabrication, and machinery assembly where durable fastening solutions are essential.

Specification Summary & Compliance

These screws feature 10-24 UNC coarse threads with standard Class 2A tolerance for reliable fit and consistent performance. The 5/16" length and fully threaded design provide complete fastening coverage, while the pan head style offers a low-profile installation. Manufactured in compliance with ASME B18.6.3 and SAE J933 standards, these screws ensure dimensional accuracy and performance reliability. The product meets industry specifications for thread cutting screws Type F and is designed for use with No. 19 drill bit (0.166" diameter) for proper hole preparation. The right-hand thread direction and zinc-plated steel material provide corrosion resistance suitable for various industrial applications.
