S-91715A146 10-32 x 3/4" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient self-tapping installation with Type F thread cutting design, eliminating the need for pre-tapped holes in materials like aluminum and sheet metal
• Enhanced driving stability through Phillips No. 2 drive and pan head design, reducing cam-out and improving torque transmission
• Reliable fine thread engagement with 10-32 UNF threading, providing superior vibration resistance and secure fastening in brass and cast iron
• Full-length threading capability ensuring maximum grip strength and uniform load distribution across the entire fastener length
• Industry-standard compliance meeting ASME B18.6.3 and RoHS 3 regulations, guaranteeing consistent quality and environmental safety
• Optimized material compatibility specifically engineered for aluminum, brass, cast iron, and sheet metal applications with recommended No. 17 drill bit size

Professional Applications & Engineering Value

These 10-32 UNF tapping screws deliver exceptional engineering value in metal fabrication and assembly operations. The thread cutting design with Type F tapping method creates precise mating threads in ductile materials, eliminating costly tapping operations and reducing assembly time. The black zinc-plated steel construction provides reliable corrosion protection while maintaining the high tensile strength required for structural applications. Particularly valuable in sheet metal assemblies and cast iron components, these screws maintain thread integrity under vibration and thermal cycling. The Phillips drive system with pan head profile ensures flush mounting and consistent clamping force, making them ideal for electrical enclosures, machinery guards, and automotive components where fine thread spacing prevents loosening in high-vibration environments.

Specification Summary & Compliance

These tapping screws feature precise 10-32 UNF fine threads with standard Class 2A tolerances for consistent engagement. The manufacturing process strictly adheres to ASME B18.6.3 specifications (referencing SAE J933) ensuring dimensional accuracy and performance reliability. Environmental compliance is maintained through RoHS 3 (2015/863/EU) certification, confirming the absence of restricted hazardous substances. The complete thread cutting screw system is optimized for use with No. 17 drill bits (0.173" diameter) in aluminum, brass, cast iron, and sheet metal applications, providing engineers with a standardized, compliant fastening solution.
