S-99512A265 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP15 drive for reduced cam-out and increased tool life in high-volume assembly
• Reliable thread formation in plastics using TRS (Thread Rolling Screw) tri-lobe shank design that displaces material without creating chips
• Enhanced corrosion resistance through zinc-plated steel construction for extended service life in various industrial environments
• Optimized plastic fastening performance with blunt tip and 19 threads per inch configuration that minimizes stress cracking
• Secure seating and consistent clamp force with standard pan head design that provides excellent bearing surface contact
• Streamlined installation process with compatible 1/8" drill bit size recommendation for precise hole preparation
• Global regulatory compliance meeting RoHS 3 and REACH standards for international manufacturing applications

Professional Applications & Engineering Value

These No. 6 x 3/4" TRS thread forming screws deliver exceptional value in plastic assembly applications where traditional fastening methods often cause material failure. The tri-lobe shank design and thread forming technology create strong, permanent threads in plastic substrates without generating debris that could compromise electronic components or moving parts. The Torx Plus IP15 drive system provides superior torque transfer compared to conventional drives, significantly reducing installation time and preventing fastener damage during high-speed assembly operations. Manufactured from zinc-plated steel, these screws maintain their integrity in environments where moisture or chemical exposure might degrade performance. The combination of 19 threads per inch pitch and blunt tip configuration ensures optimal holding power while minimizing the risk of plastic boss cracking, making them ideal for automotive trim, electronic enclosures, and consumer products requiring reliable plastic-to-plastic or plastic-to-metal connections.

Specification Summary & Compliance

These inch-system fasteners feature a No. 6 thread diameter (0.138") with 19 threads per inch and 3/4" length in fully threaded configuration. The TRS (Thread Rolling Screw) tapping method follows industry standards for thread forming applications in plastics. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety for global industrial applications. The pan head design with 0.27" diameter and Torx Plus IP15/T15 drive provides consistent performance across manufacturing environments.
