S-90087A249 10-24 x 1 1/4" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating for extended service life in demanding industrial environments
• Excellent self-tapping performance with Type F thread cutting design for reliable installation in aluminum, brass, cast iron, and sheet metal
• Optimized driving efficiency with No. 2 Phillips drive providing secure tool engagement and reduced cam-out risk
• Enhanced load distribution through pan head design that prevents surface damage while maintaining strong clamping force
• Maximum thread engagement with full threading along the 1 1/4" length for superior holding power in various material thicknesses
• Quick installation advantage with UNC coarse threads that reduce driving torque and minimize cross-threading incidents
• Industry-standard compatibility with pre-drilled No. 17 holes (0.173" diameter) for streamlined assembly processes

Professional Applications & Engineering Value

These 10-24 zinc-plated steel tapping screws deliver exceptional engineering value by solving critical fastening challenges in metal fabrication and assembly operations. The Type F thread cutting design with blunt tip and UNC coarse threading creates precise mating threads without requiring pre-tapped holes, significantly reducing installation time and labor costs. The zinc-plated steel construction provides essential corrosion protection for applications in aluminum, brass, cast iron, and sheet metal where environmental exposure is a concern. The Phillips pan head configuration offers optimal drive stability while the rounded profile minimizes surface marring, making these self-tapping screws ideal for electrical enclosures, machinery panels, automotive components, and HVAC systems where both performance and aesthetics matter.

Specification Summary & Compliance

These industrial fasteners feature Class 2A thread tolerances with UNC 10-24 coarse thread specification and comply with ASME B18.6.3 standards (SAE J933) for dimensional accuracy and performance reliability. The manufacturing process adheres to RoHS 3 (2015/863/EU) compliance requirements, ensuring environmental responsibility while maintaining the mechanical properties necessary for demanding tapping screw applications across various metal substrates.
