Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
- Efficient self-tapping installation with Type F thread cutting design eliminates need for pre-tapped holes in aluminum, brass, cast iron, and sheet metal
- Enhanced load distribution through integrated flange design reduces surface pressure and prevents pull-through in thin materials
- Versatile drive options with combined external hex/slotted head accommodate both wrench and screwdriver applications
- Reliable fine thread engagement with 10-32 UNF threading provides superior vibration resistance and precise fastening
- Full-length threading ensures maximum grip strength and consistent performance across the entire 2 1/2" length
- Industry-standard compliance meets ASME B18.6.3 specifications and RoHS 3 environmental regulations for quality assurance
Professional Applications & Engineering Value
Engineered for heavy-duty fastening in aluminum, brass, cast iron, and sheet metal assemblies, these 10-32 UNF thread cutting screws solve critical installation challenges in manufacturing and metalworking applications. The zinc-plated steel construction provides essential corrosion protection while the Type F tapping screw design creates precise mating threads without pre-tapping operations, significantly reducing assembly time and labor costs. The flanged hex head combines wrench torque capability with built-in washer functionality, eliminating separate components while ensuring secure fastening in automotive, machinery, and structural applications where vibration resistance and long-term reliability are paramount.
Specification Summary & Compliance
This No. 10 screw with 10-32 UNF fine threads features Class 2A thread tolerances and full threading along its 2 1/2" length. Manufactured to ASME B18.6.3 specifications (SAE J933) with RoHS 3 (2015/863/EU) compliance, ensuring environmental regulatory adherence. The thread cutting design requires an 11/64" (0.1719") drill bit for proper installation in specified materials, delivering consistent performance meeting industrial fastener standards for dimensional accuracy and mechanical properties.
