S-90925A201 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments
• Maximum torque transmission with T20 Torx drive design, reducing cam-out and tool slippage during installation
• Secure thread-forming fastening that creates strong, permanent threads in sheet metal up to 0.025" thickness
• Full threading along the 1-1/4" length provides consistent holding power throughout the entire fastener engagement
• Optimized No. 8-15 thread pitch (15 threads per inch) delivers excellent pull-out resistance in sheet metal applications
• Pan head design with rounded profile offers a finished appearance while providing good bearing surface
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These No. 8 sheet metal tapping screws are specifically engineered to solve common fastening challenges in metal fabrication and assembly operations. The thread forming design eliminates the need for pre-tapped holes, creating strong internal threads that resist vibration loosening and provide superior pull-out strength compared to traditional fastening methods. The zinc-plated steel construction delivers essential corrosion protection for industrial environments, while the T20 Torx drive system enables higher torque application without stripping the drive recess - a critical advantage in high-volume production settings where consistent fastening force is paramount. These A/AB type tapping screws are particularly valuable in HVAC systems, electrical enclosures, and machinery panels where reliable sheet metal fastening is essential for structural integrity.

Specification Summary & Compliance

This thread forming screw features precise No. 8-15 thread specifications with 0.164" diameter and fully threaded 1-1/4" length, manufactured to standard tolerances for consistent performance. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory compliance for industrial applications. Designed for use with No. 29 drill bit (0.136" diameter) in materials up to 0.025" thickness, these right-hand threaded fasteners provide reliable performance in demanding sheet metal fastening scenarios.
