Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
- Excellent thread-forming capability creates strong, permanent threads in various materials without pre-tapping
- Optimized torque transfer through No. 2 Phillips drive design reduces cam-out risk and installation time
- Wide material compatibility for reliable fastening in steel, aluminum, brass, cast iron, and sheet metal applications
- Precise UNF fine threading ensures secure, vibration-resistant connections in critical assemblies
- Full threading along entire shank provides maximum grip strength and uniform load distribution
- Regulatory compliance assurance with RoHS 3 and REACH standards for global industrial safety requirements
Professional Applications & Engineering Value
These 10-32 UNF thread forming screws deliver exceptional engineering value through their specialized zinc-plated steel construction and SW tapping screw design. The thread forming action creates precise, strong threads in parent materials without generating chips, eliminating contamination risks in sensitive assemblies. The No. 2 Phillips drive ensures efficient installation with standard tools while the 0.19" thread diameter and fine UNF threading provide excellent pull-out resistance in thin-section materials like sheet metal. These characteristics make them ideal for automotive components, electrical enclosures, machinery frames, and fabricated metal products where vibration resistance and long-term reliability are critical.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread tolerances for consistent performance. Features UNF fine thread specification (10-32) with right-hand threading and 0.18" recommended drill size. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial safety. The fully threaded design with 0.373" pan head diameter and 3/8" length ensures reliable fastening across multiple material thicknesses.
