S-92750A256 10-24 x 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Enhanced torque transmission through Torx T25 drive system, reducing cam-out and tool slippage during installation
• Excellent thread-forming capability with Tri-Lobe shank design that creates strong, permanent threads in sheet metal without pre-tapping
• Optimized for sheet metal applications with coarse UNC 10-24 threading that provides superior pull-out resistance
• Secure fastening performance through fully threaded design that maintains consistent clamping force along the entire engagement length
• Streamlined assembly process with standard pan head profile that sits flush against surfaces while accommodating standard drill bit sizes
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in sheet metal assembly applications where reliable thread formation is critical. The Tri-Lobe shank cross-section displaces material during installation, creating precisely formed threads that eliminate the need for additional tapping operations. This thread forming capability significantly reduces assembly time while providing vibration-resistant fastening joints. The Torx T25 drive system ensures maximum torque transfer, preventing driver slippage that can damage screw heads and compromise installation integrity. With coarse UNC 10-24 threading and blunt tip design, these screws are engineered for rapid installation in various sheet metal thicknesses while maintaining consistent clamping force through the fully threaded configuration. The zinc plating provides essential corrosion protection, making these fasteners suitable for both indoor and moderate outdoor environments.

Specification Summary & Compliance

These 10-24 x 3/8" tapping screws feature precision UNC coarse threads with standard thread tolerances for consistent performance. The fasteners comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current international compliance standards. Engineered for use with No. 21 drill bits (0.159" diameter), these thread-forming screws incorporate Tri-Lobe shank technology that creates secure, permanent threads in sheet metal substrates without requiring pre-tapped holes. The Torx T25 drive system provides reliable installation performance, while the zinc-plated steel construction delivers both strength and corrosion resistance for long-term fastening reliability.
