S-90096A307 8-32 x 1/4" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior Thread-Cutting Performance – Self-tapping design eliminates the need for pre-tapped holes, reducing installation time and labor costs in production environments
• Enhanced Corrosion Resistance – Zinc-plated steel construction provides reliable protection against rust and oxidation, extending service life in demanding industrial settings
• High-Torque Installation Capability – External hex head design enables maximum torque application with standard tools, preventing stripping and ensuring secure fastening
• Integrated Flange Design – Built-in flange distributes clamping pressure evenly, reducing surface damage and maintaining joint integrity in sheet metal applications
• Broad Material Compatibility – Specifically engineered for reliable performance in aluminum, brass, cast iron, and sheet metal without requiring separate inserts
• Industry-Standard Coarse Threading – 8-32 UNC coarse thread profile ensures quick engagement and superior holding power in various materials
• Full Thread Engagement – Completely threaded shank maximizes grip strength and pull-out resistance across the entire fastener length

Professional Applications & Engineering Value

This thread cutting screw delivers exceptional engineering value by solving critical fastening challenges in metal fabrication and assembly operations. The Type F tapping screw design with coarse UNC threading and blunt tip creates precise mating threads in ductile materials without chip accumulation, eliminating the need for expensive tapping operations. The zinc-plated steel construction combined with the flanged hex head provides corrosion resistance while the external drive system withstands high installation torque, making it ideal for sheet metal enclosures, aluminum frames, brass fittings, and cast iron components. The integrated flange acts as a built-in washer, distributing load effectively and preventing loosening under vibration – a common failure point in industrial equipment and machinery assemblies.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 8-32 UNC coarse thread profile and Class 2A tolerance for consistent performance. Fully compliant with ASME B18.6.3 specifications (SAE J933) for quality assurance in industrial applications. Meets RoHS 3 (2015/863/EU) compliance requirements for environmental safety. Designed for use with No. 26 drill bit (0.147" diameter) for proper hole preparation. Right-hand thread direction and fully threaded design ensure maximum engagement in approved materials including aluminum, brass, cast iron, and sheet metal.
