S-94059A249 Length 1 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
• Integrated sealing protection through steel/rubber washer that prevents moisture ingress and maintains joint integrity
• Self-drilling capability with No. 3 drill tip that eliminates pre-drilling requirements, saving installation time and labor costs
• High-strength thread forming design creates permanent, vibration-resistant threads in steel and sheet metal up to 0.15" thickness
• Secure external hex drive provides positive torque transmission and prevents stripping during high-torque applications
• Full threading ensures maximum grip length and uniform stress distribution across the entire fastened joint
• BSD tapping screw configuration delivers reliable performance in various metal fastening applications

Professional Applications & Engineering Value

This No. 10-16 zinc-plated steel tapping screw addresses critical challenges in metal fabrication and assembly operations. The combination of thread forming technology and integrated sealing washer provides dual functionality - creating strong, permanent threads while simultaneously protecting against environmental contaminants. The external hex drive ensures reliable installation with standard tools, reducing the risk of fastener failure in high-vibration environments. Particularly valuable in sheet metal applications and steel constructions, this fastener's drilling tip penetrates up to 0.15" thickness without pilot holes, streamlining production workflows. The fully threaded design maximizes engagement in varying material thicknesses, making it ideal for HVAC systems, electrical enclosures, and industrial equipment where sealing capability and corrosion resistance are paramount.
