S-90096A192 8-32 x 3/8" 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
• Maximum torque transfer through external hex/slotted drive design, preventing tool slippage during installation
• Enhanced holding power with fully threaded UNC coarse spacing that provides superior pull-out resistance in various materials
• Eliminates need for separate washers thanks to integrated flange design that distributes load evenly
• Self-tapping capability with Type F thread cutting design that creates precise mating threads in aluminum, brass, cast iron, and sheet metal
• Reliable performance assurance through compliance with ASME B18.6.3 standards and RoHS 3 environmental regulations
• Optimized for industrial applications with No. 26 drill bit compatibility for precise pre-drilling requirements

Professional Applications & Engineering Value

This 8-32 zinc-plated steel tapping screw delivers exceptional engineering value by addressing common fastening challenges in metal fabrication and assembly operations. The Type F thread cutting design eliminates the need for pre-tapped holes, significantly reducing installation time and labor costs while creating strong, permanent threads in materials ranging from soft aluminum alloys to tougher cast iron. The external hex/slotted drive system provides dual-tool compatibility, ensuring reliable installation even in confined spaces. The integrated flange design acts as a built-in washer, preventing material distortion in thin sheet metal applications while providing superior clamp load distribution. These heavy-duty tapping screws maintain consistent performance across temperature variations and vibration-prone environments, making them ideal for automotive components, electrical enclosures, machinery assemblies, and structural metal frameworks where UNC coarse thread reliability is paramount.

Specification Summary & Compliance

This No. 8 tapping screw features precise 8-32 UNC coarse thread specifications with Class 2A tolerance for consistent fit and performance. Manufactured to meet ASME B18.6.3 standards (where identified as SAE J933) for dimensional accuracy and mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant, ensuring environmental responsibility while maintaining the high-performance characteristics required for industrial fastening applications. The zinc-plated steel construction provides reliable corrosion protection, while the blunt tip and fully threaded design ensure optimal thread engagement and holding strength in specified materials.
