S-90066A823 Length 1" 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 vibration resistance and sealing through integrated steel/rubber washer that prevents loosening and provides reliable performance
• Quick and secure installation with 3/8" external hex head design allowing for high-torque application with standard tools
• Optimal thread forming capability with A/AB tapping screw design that creates strong, permanent threads in sheet metal without pre-tapping
• Maximum material penetration with fully threaded 1" length and pointed tip for efficient driving through up to 0.025" thickness
• Precise installation compatibility with standardized 1/4" drill bit requirement for consistent, reliable fastening results
• Durable thread retention with 0.281" diameter and 10 threads per inch providing secure, long-lasting fastening in sheet metal applications

Professional Applications & Engineering Value

These No. 17 zinc-plated steel tapping screws are specifically engineered to address common challenges in sheet metal fabrication and assembly. The thread forming design eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger, more reliable threads that won't strip under vibration or stress. The combination of zinc-plated steel construction and integrated steel/rubber washer provides dual protection against corrosion and vibration-induced loosening, making these external hex drive screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where reliable fastening performance is critical. The fully threaded configuration with pointed tip ensures maximum grip length and easy starting in pre-drilled holes.
