S-90096A367 6-32 x 5/16" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Efficient installation and removal enabled by the external hex/slotted drive, providing compatibility with multiple tools for faster assembly.
• Eliminates the need for pre-tapped holes with its thread-cutting Type F design, saving time and labor costs in materials like aluminum and sheet metal.
• Enhanced holding power and stability from the integrated flange, which acts as a built-in washer to distribute load and prevent loosening.
• Reliable performance in various metals including brass and cast iron, thanks to the coarse UNC thread and fully threaded shank for maximum grip.
• Streamlined inventory management by complying with ASME B18.6.3 and RoHS 3 standards, ensuring consistent quality and regulatory adherence.
• Optimized for high-volume applications with a blunt tip and 6-32 UNC thread size, reducing cross-threading risks and improving assembly speed.

Professional Applications & Engineering Value

This 6-32 UNC zinc-plated steel flanged tapping screw is engineered to solve common fastening challenges in industrial assembly. Its thread-cutting Type F design allows for direct installation into ductile materials like aluminum, brass, cast iron, and sheet metal, eliminating the need for separate tapping operations and reducing production time. The coarse UNC thread and fully threaded shank ensure strong, reliable engagement in soft metals, while the zinc plating provides a durable barrier against corrosion, extending the lifespan of assemblies in harsh conditions. The integrated flange distributes clamping force evenly, minimizing the risk of material damage and vibration-induced loosening. Ideal for high-volume manufacturing, this screw enhances efficiency and reliability in automotive, machinery, and metal fabrication applications.
