S-93882A236 8-32 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Enhanced installation efficiency through external hex drive design that prevents tool slippage and ensures secure fastening
• Exceptional material compatibility with thread-forming design that creates strong, permanent threads in steel, aluminum, brass, cast iron, and sheet metal
• Maximum holding power achieved through fully threaded UNC coarse spacing that distributes load evenly across the entire fastener length
• Reduced assembly time with integrated flange that eliminates the need for separate washers while providing wider bearing surface
• Reliable performance with blunt tip design that prevents material splitting during installation in thin-section applications
• Optimized drill compatibility designed for use with standard No. 26 drill bit (0.146" diameter) for precise hole preparation

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value through their thread-forming SW design that eliminates the need for pre-tapped holes, significantly reducing assembly time and labor costs. The UNC coarse threading provides superior pull-out resistance in softer materials like aluminum and sheet metal, while the fully threaded construction ensures maximum engagement strength across the entire fastener length. The external hex drive allows for high-torque installation without cam-out, making these flanged screws ideal for automotive, electrical enclosure, and machinery applications where vibration resistance and reliable fastening are critical. The combination of zinc plating and steel substrate offers excellent corrosion protection for both indoor and outdoor industrial environments.
