S-90096A388 10-32 x 1 3/4" 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 environments
• Excellent thread-cutting capability with Type F design creates precise threads in aluminum, brass, cast iron and sheet metal without pre-tapping
• Enhanced fastening stability through the flanged design that distributes load evenly and prevents pull-through
• Versatile installation options with external hex/slotted drive for both wrench and screwdriver applications
• Maximum holding power achieved through full threading along the entire 1-3/4" length for superior grip strength
• Precise fit and compatibility with 10-32 UNF fine thread specification ensuring reliable performance in industrial assemblies
• Reduced installation complexity with pre-determined 11/64" drill bit size for accurate hole preparation

Professional Applications & Engineering Value

This 10-32 UNF tapping screw delivers exceptional engineering value in metal fabrication and assembly operations. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for demanding applications. The thread cutting design (Type F) eliminates the need for separate tapping operations, significantly reducing installation time and labor costs in aluminum, brass, cast iron, and sheet metal components. The combination of external hex/slotted drive offers flexibility for both high-torque wrench applications and precision screwdriver use. The flanged head design provides superior bearing surface, preventing damage to softer materials while ensuring secure fastening in vibration-prone environments common in industrial machinery, electrical enclosures, and automotive assemblies.

Specification Summary & Compliance
