S-90096A381 10-24 x 1 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.
• Robust external hex/slotted drive provides excellent torque transmission and tool compatibility, preventing cam-out for secure, efficient installation.
• Integrated flange design distributes clamping pressure over a wider area, enhancing joint stability and reducing the risk of surface damage.
• Coarse UNC 10-24 thread ensures rapid installation and high resistance to vibration loosening in sheet metal and other applications.
• Fully threaded blunt tip allows for easy starting and consistent engagement depth, improving assembly speed and reliability.
• Compliance with ASME B18.6.3 and RoHS 3 guarantees consistent quality, dimensional accuracy, and environmental safety for global supply chains.

Professional Applications & Engineering Value

These 10-24 zinc-plated steel tapping screws are engineered to solve common fastening challenges in metalworking and fabrication. The thread cutting (Type F) design is specifically formulated for use in aluminum, brass, cast iron, and sheet metal, where it forms clean, strong threads without pre-tapping, significantly reducing assembly time and labor costs. The external hex/slotted drive accommodates both manual and powered tools, offering versatility on the production line. The combination of a coarse UNC thread and a flanged head provides exceptional pull-out resistance and clamping force, making these screws ideal for vibration-prone applications in automotive, machinery, and electrical enclosures. This design ensures reliable, long-lasting connections that withstand operational stresses.
