Professional Applications & Engineering Value

These 10-32 UNF thread cutting screws are engineered to solve critical fastening challenges in aluminum, brass, cast iron, and sheet metal applications. The Type F tapping screw design with thread cutting capability eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the flanged hex head combines the high torque capability of external hex drives with the added stability of an integrated washer face. This combination addresses common issues of joint loosening and material stripping in soft metals and thin sheet materials, making these screws ideal for manufacturing, automotive, and metal fabrication applications where reliability and efficiency are paramount.

Specification Summary & Compliance

This No. 10 tapping screw features 10-32 UNF fine threads with standard thread tolerances and full threading along the 1-1/4" length. Manufactured in compliance with ASME B18.6.3 specifications (referencing SAE J933) for dimensional accuracy and performance standards. The product meets RoHS 3 (2015/863/EU) compliance requirements, ensuring environmental safety and regulatory adherence for industrial use. Recommended drill bit size for proper installation is 11/64" (0.1719" diameter) to achieve optimal thread engagement and holding strength.
