S-90096A380 10-24 x 1/4" 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.
• High-strength thread cutting action (Type F) creates precise internal threads in materials like aluminum and cast iron, eliminating the need for pre-tapped holes.
• Versatile external hex/slotted drive offers compatibility with a wide range of tools for efficient installation and removal.
• Integrated flange design provides a larger bearing surface for improved load distribution and prevents pull-through in sheet metal applications.
• Coarse UNC thread ensures rapid installation and superior holding power in brittle or soft materials.
• Fully threaded shank maximizes grip length and provides consistent clamping force along the entire fastener.
• Precision-engineered dimensions ensure reliable performance and interchangeability, backed by compliance with major industry standards.

Professional Applications & Engineering Value

These 10-24 zinc-plated steel tapping screws are engineered to solve critical fastening challenges in metalworking and assembly. The thread cutting design (Type F) with a blunt tip and coarse UNC thread allows them to form strong, clean threads directly in aluminum, brass, cast iron, and sheet metal, significantly reducing assembly time and labor costs by eliminating a separate tapping operation. The zinc plating provides a durable barrier against corrosion, essential for components exposed to varying environmental conditions. Combined with the versatile external hex/slotted drive and flanged head, these screws deliver a reliable, high-strength fastening solution that enhances the integrity and longevity of your industrial assemblies.
