Professional Applications & Engineering Value
These 6-32 UNC zinc-plated steel tapping screws deliver exceptional engineering value by solving critical fastening challenges in metalworking applications. The specialized thread cutting design (Type F) enables direct installation into aluminum, brass, cast iron, and sheet metal without separate tapping operations, significantly reducing assembly time and labor costs. The coarse UNC threading provides maximum resistance to vibration loosening while the zinc-plated steel construction ensures reliable performance in environments where corrosion resistance is essential. The No. 2 Phillips drive and pan head design offer optimal torque transmission and surface contact, making these tapping screws ideal for electrical enclosures, machinery panels, and automotive components where secure, permanent fastening is required.
Specification Summary & Compliance
These 5/16" length tapping screws feature precise 6-32 UNC coarse threads with standard Class 2A thread tolerances for consistent performance. Manufacturing strictly adheres to ASME B18.6.3 specifications (SAE J933) ensuring dimensional accuracy and mechanical properties. The products are fully RoHS 3 (2015/863/EU) compliant and manufactured using environmentally responsible processes. The Type F thread cutting design is optimized for use with No. 31 drill bits (0.12" diameter) in the specified materials, providing engineers with reliable, standardized fastening solutions.
