S-90087A851 6-32 x 7/16" 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
• Effortless installation with thread-cutting Type F design that creates mating threads without pre-tapping in aluminum, brass, cast iron, and sheet metal
• Secure fastening through coarse UNC threads providing excellent pull-out resistance in various materials
• Reliable drive engagement with No. 2 Phillips drive preventing cam-out during high-torque installation
• Optimized material compatibility with recommended No. 31 drill bit size (0.12") for precise hole preparation
• Full-length threading ensures maximum thread engagement and holding power across the entire 7/16" length
• Industry-standard compliance meeting ASME B18.6.3 and SAE J933 specifications for consistent quality and performance

Professional Applications & Engineering Value

These 6-32 UNC zinc-plated steel tapping screws deliver exceptional engineering value in industrial fastening applications where material integrity and installation efficiency are critical. The thread-cutting Type F design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in aluminum, brass, cast iron, and sheet metal components. The coarse UNC thread form provides superior resistance to vibration loosening while the zinc-plated steel construction offers reliable corrosion protection in moderate environments. The pan head with No. 2 Phillips drive ensures flush mounting and secure tool engagement, making these tapping screws ideal for electrical enclosures, machinery panels, automotive assemblies, and general metal fabrication where fully threaded fasteners are required for maximum holding strength.

Specification Summary & Compliance

These tapping screws feature precise 6-32 UNC coarse threads with standard Class 2A thread tolerances, ensuring consistent fit and performance. The 7/16" length and 0.138" thread diameter maintain dimensional accuracy per manufacturing specifications. Compliance with ASME B18.6.3 and SAE J933 standards guarantees mechanical properties and performance reliability. The zinc-plated steel material meets industry requirements for corrosion resistance while the thread-cutting Type F design follows established engineering protocols for self-tapping fasteners in metal applications.
