S-92750A058 2-56 x 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced torque transmission through T8 Torx drive design, reducing cam-out and tool slippage during installation
• Secure fastening in sheet metal achieved through tri-lobe shank design that creates permanent, vibration-resistant threads
• Reliable thread forming capability with UNC coarse threads and blunt tip for easy starting without pre-tapping requirements
• Optimized for high-volume assembly with fully threaded design and right-hand threading for rapid installation
• Industry-standard compatibility with No. 48 drill bits and CA-type thread forming specifications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These 2-56 UNC thread forming screws are specifically engineered for sheet metal applications where reliable fastening is critical. The zinc-plated steel construction provides essential corrosion protection while maintaining structural integrity. The tri-lobe shank cross-section displaces material during installation, creating permanent threads that resist vibration loosening - a common failure point in dynamic assemblies. The T8 Torx drive system delivers superior torque transmission compared to traditional drive types, reducing installation time and preventing fastener damage. With coarse UNC threading and blunt tip design, these screws eliminate the need for pre-tapped holes, streamlining production processes in sheet metal fabrication, electronic enclosures, and HVAC assemblies where speed and reliability are paramount.

Specification Summary & Compliance

These precision tapping screws feature 2-56 UNC coarse threads with standard Class 2A tolerance, ensuring consistent performance across manufacturing applications. The 1/4" length and pan head design provide optimal clearance and clamping force distribution. Manufactured to CA-type thread forming specifications with tri-lobe shank geometry, these screws are designed for use with No. 48 drill bits (0.076" diameter). Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards ensures they meet the strictest international regulatory requirements for industrial components.
