S-90087A250 10-24 x 1 1/2" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior Thread Cutting Performance: Self-tapping Type F design eliminates the need for pre-tapped holes, reducing installation time and labor costs in aluminum, brass, cast iron, and sheet metal.
• Enhanced Corrosion Resistance: Zinc-plated steel construction provides a durable barrier against rust and oxidation, ensuring long-term reliability in demanding industrial environments.
• Optimized Drive Efficiency: Phillips No. 2 drive offers a secure fit with standard tools, minimizing cam-out and preventing damage to the screw head for faster, more reliable assembly.
• Excellent Holding Power: UNC coarse threading ensures rapid installation and provides a strong, secure grip in a wide range of base materials, preventing loosening under vibration.
• Full-Length Thread Engagement: Fully threaded 1-1/2" length maximizes contact area for a more uniform and robust connection, enhancing the overall joint strength.
• Streamlined Sourcing & Compatibility: Complies with ASME B18.6.3 and SAE J933 standards, guaranteeing dimensional consistency and interchangeability with other compliant components.
• Simplified Installation Process: Designed for use with a standard No. 17 drill bit (0.173" diameter), streamlining the preparation process and reducing the risk of errors.

Professional Applications & Engineering Value

These 10-24 x 1-1/2" zinc-plated steel tapping screws are engineered to solve critical assembly challenges in metalworking and manufacturing. The Type F thread cutting design is specifically formulated to create strong, clean threads in ductile materials like aluminum, brass, cast iron, and sheet metal without the need for a separate tapping operation. This eliminates a production step, significantly reducing assembly time and cost. The zinc plating provides essential corrosion protection, extending the service life of assemblies exposed to harsh conditions. The combination of a Phillips drive and UNC coarse thread ensures quick, high-torque installation with common tools, making them an ideal, high-efficiency industrial fastener for high-volume production lines and maintenance repairs.
