S-97349A425 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 various environments without rust or degradation.
• Efficient thread forming design creates strong, permanent threads in plastic materials, reducing the risk of stripping and providing excellent pull-out resistance.
• Easy installation and reduced cam-out with Phillips drive and No. 2 size, allowing for quick, secure fastening with standard tools while minimizing driver slippage.
• Optimized for plastic applications featuring a blunt tip and fully threaded shank to prevent material cracking and ensure consistent, reliable holding power.
• Wide compatibility and precise fit with standardized dimensions (0.138" thread diameter, 19 TPI) and pan head design for flush or low-profile fastening in plastic assemblies.
• Environmental and regulatory compliance meeting RoHS 3 and REACH standards, making them safe for use in regulated industries and global markets.
• Durable, fully threaded construction maximizes grip length and distributes stress evenly, enhancing joint integrity in demanding plastic fastening tasks.

Professional Applications & Engineering Value

These No. 6 x 1-1/4" tapping screws are specifically engineered for plastic fastening applications, where traditional screws may cause cracking or weak threads. The 18-8 stainless steel material offers excellent corrosion resistance, ideal for outdoor or humid environments, while the thread forming (DST type) design displaces plastic material to create strong, load-bearing threads without chips. This eliminates the need for pre-tapped holes, speeding up assembly and reducing labor costs. The Phillips pan head and blunt tip ensure easy, controlled installation in brittle plastics like PVC, polycarbonate, or ABS, commonly used in electronics enclosures, automotive components, and consumer products. By combining fully threaded coverage with precise 0.138" diameter and 19 TPI, these screws deliver consistent clamping force and vibration resistance, solving common issues like loosening or material failure in plastic assemblies.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 6 screw size, 1-1/4" length, and fully threaded shank. Thread specifications include a 0.138" diameter and 19 threads per inch, designed for use with a No. 32 drill bit (0.116" diameter) in plastic materials. The tapping method is thread forming (DST), and the screw meets common industry standards for dimensional accuracy. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring the absence of hazardous substances and suitability for environmentally conscious manufacturing processes.
