S-90096A363 1/2"-13 x 2" 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 transmission through external hex drive design, preventing tool slippage during high-torque installation
• Eliminates separate washer requirements with integrated flange design that distributes clamping force over wider surface area
• Exceptional thread-cutting performance in multiple materials including aluminum, brass, cast iron and sheet metal without pre-tapped holes
• Enhanced holding power through fully threaded design that maintains consistent engagement along the entire fastener length
• Reliable coarse thread engagement with UNC 1/2"-13 threading for quick installation and reduced cross-threading risks
• Industry-standard compliance meeting ASME B18.6.3 specifications and RoHS 3 environmental regulations

Professional Applications & Engineering Value

Engineered for heavy-duty thread cutting applications, these zinc-plated steel tapping screws provide exceptional value in industrial assembly operations. The F-type thread cutting design combined with coarse UNC threading creates precise mating threads in ductile materials like aluminum, brass, and cast iron without requiring pre-tapped holes, significantly reducing installation time and labor costs. The integrated flange eliminates the need for separate washers while providing superior load distribution, preventing material deformation in sheet metal applications. With external hex drive compatibility, these screws accommodate standard industrial tools for high-torque installation in confined spaces, making them ideal for machinery assembly, structural frameworks, and metal fabrication where reliable fastening performance is critical.

Specification Summary & Compliance
