Key Features & Benefits at a Glance
- Corrosion-resistant zinc plating extends service life in demanding industrial environments
- Self-tapping F-type thread design eliminates need for separate tapping operations, reducing assembly time and labor costs
- No. 2 Phillips drive provides secure tool engagement and prevents cam-out during high-torque installation
- 10-32 UNF fine thread spacing delivers superior holding power in thin materials and vibration-prone applications
- Pan head profile with 0.373" diameter offers excellent bearing surface for secure fastening without sinking
- Full threading along 5/16" length ensures maximum thread engagement and pull-out resistance
- Universal material compatibility performs reliably in aluminum, brass, cast iron, and sheet metal applications
Professional Applications & Engineering Value
These 10-32 UNF thread cutting screws are engineered to solve critical fastening challenges in metalworking and manufacturing applications. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength. The F-type tapping screw design with blunt tip and fine thread spacing creates precise, clean threads in pre-drilled holes (recommended 11/64" drill bit), eliminating cross-threading and material deformation issues. This makes them ideal for sheet metal assemblies, aluminum enclosures, and cast iron components where vibration resistance and thread integrity are paramount. The combination of No. 2 Phillips drive and pan head design ensures quick installation and reliable clamping force distribution across the fastened surface.
Specification Summary & Compliance
These tapping screws feature Class 2A thread tolerances per UNF standard with 0.19" thread diameter and fully threaded 5/16" length. Manufacturing and performance comply with ASME B18.6.3 and SAE J933 specifications, ensuring consistent quality and dimensional accuracy. The zinc-plated steel material meets industry standards for corrosion resistance and mechanical properties, suitable for various industrial fastening applications requiring reliable performance and compliance with engineering specifications.
