S-92715A340 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
• Enhanced load distribution through integrated 0.493" flat washer that prevents surface damage and maintains joint integrity
• Reduced installation time with self-drilling No. 2 tip that eliminates pre-drilling requirements up to 0.098" thickness
• Exceptional thread retention through BSD thread-forming technology that creates strong, permanent threads in base materials
• Improved driving control with Phillips No. 2 drive design that minimizes cam-out and ensures secure fastening
• Wide surface contact from truss head profile that provides superior clamping force across larger areas
• Versatile material compatibility for reliable performance in steel, fabric, and sheet metal applications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional engineering value by solving critical fastening challenges in metal fabrication and industrial assembly. The combination of thread-forming BSD technology and self-drilling tip eliminates the need for separate tapping operations, significantly reducing installation time and labor costs. The fully threaded design ensures maximum engagement throughout the entire 1-1/4" length, providing superior pull-out resistance in sheet metal applications. The integrated flat washer distributes clamping forces evenly, preventing material distortion in thin-gauge steel and fabric components. This comprehensive fastening solution maintains consistent performance across various material thicknesses while the Phillips drive offers reliable installation control for production line efficiency.

Specification Summary & Compliance

This No. 8 tapping screw features precise 0.164" thread diameter with 18 threads per inch in right-hand orientation, manufactured to industry standards for consistent performance. The thread-forming BSD design creates permanent threads without chip removal, while the zinc-plated steel construction provides corrosion protection. The screw meets applicable industrial specifications for tapping screws in metal applications, with dimensional accuracy ensuring reliable engagement and clamping performance across recommended material types.
