S-93945A019 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh environments
• High-torque installation capability thanks to the square drive design, preventing cam-out and reducing tool wear
• Excellent thread-forming performance with Type A/AB tapping screw design, creating strong threads in sheet metal without pre-tapping
• Optimal material compatibility with 0.025" maximum drilling thickness and No. 29 drill bit specification for precise sheet metal applications
• Secure flush mounting with standard 82° flat head profile that sits perfectly countersunk in materials
• Full-length threading provides maximum grip and holding power across the entire 1-1/4" length
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These Type A/AB tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The 18-8 Stainless Steel composition provides outstanding corrosion resistance, making these fasteners ideal for applications exposed to moisture, chemicals, or outdoor elements. The thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs in high-volume production environments. The square drive system ensures maximum torque transfer during installation, preventing stripping and ensuring consistent clamping force. With their fully threaded No. 8-15 configuration and pointed tip, these screws penetrate sheet metal efficiently while creating durable, vibration-resistant connections that maintain integrity under stress.

Specification Summary & Compliance

This No. 8-15 x 1-1/4" tapping screw features precise right-hand threads with standard thread forming specifications for consistent performance. The fastener maintains dimensional accuracy with a 0.164" thread diameter and 15 threads per inch configuration. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and regulatory acceptance for industrial applications worldwide. The flat head design incorporates an 82° countersink angle for proper seating in prepared holes, while the square drive (No. 2 size) provides reliable installation performance.
