S-90096A385 10-32 x 1/4" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced material penetration through Type F thread cutting design that creates strong, permanent threads in aluminum, brass, cast iron, and sheet metal
• Increased installation efficiency with external hex/slotted drive that accommodates multiple tool types while preventing stripping
• Improved load distribution thanks to the integrated flange design that eliminates the need for separate washers
• Maximum holding power through fully threaded shank that ensures complete engagement along the entire 1/4" length
• Precise thread engagement with fine 10-32 UNF threading that provides superior vibration resistance in critical applications
• Reduced assembly steps with pre-determined 11/64" drill bit size for streamlined installation processes

Professional Applications & Engineering Value

These 10-32 UNF thread cutting screws deliver exceptional engineering value in metal fabrication and assembly operations. The Type F tapping screw design with thread cutting capability eliminates the need for pre-tapped holes, significantly reducing installation time and labor costs. Manufactured from zinc-plated steel, these fasteners provide reliable performance in aluminum, brass, cast iron, and sheet metal applications where corrosion resistance is critical. The flanged hex screw configuration offers superior clamping force distribution while the external hex/slotted drive ensures compatibility with both manual and power tools. This combination of features makes them ideal for high-volume production environments requiring consistent, repeatable fastening solutions with minimal hardware requirements.

Specification Summary & Compliance
