S-90096A417 3/8"-16 x 1" 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
• High-torque installation capability through external hex/slotted drive design for secure fastening and reduced tool slippage
• Self-tapping efficiency with thread cutting design that eliminates pre-tapping requirements in aluminum, brass, cast iron, and sheet metal
• Enhanced load distribution from the integrated flange design that provides superior clamping force and prevents pull-through
• Reliable coarse threading with UNC 3/8"-16 specification ensuring quick installation and vibration resistance in various materials
• Full-length threading for maximum grip strength and consistent fastening performance along the entire screw length
• Industry-standard compliance meeting ASME B18.6.3 specifications for guaranteed dimensional accuracy and performance reliability

Professional Applications & Engineering Value

This heavy-duty flanged tapping screw delivers exceptional engineering value through its zinc-plated steel construction and thread cutting design, specifically engineered to solve common fastening challenges in metal fabrication and assembly operations. The F-type tapping screw with coarse UNC threading creates precise mating threads in aluminum, brass, cast iron, and sheet metal applications without requiring pre-tapped holes, significantly reducing installation time and labor costs. The combination of external hex/slotted drive and integrated flange provides superior torque transmission while distributing clamping force over a wider surface area, preventing material deformation and ensuring long-term joint integrity in vibration-prone environments common to automotive, machinery, and structural applications.

Specification Summary & Compliance
