S-99512A310 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP20 drive, reducing cam-out and tool wear for efficient installation
• Reliable thread forming performance in plastic materials with TRS (Thread Rolling Screw) design, minimizing cracking and stress
• Enhanced corrosion resistance through zinc-plated steel construction, extending service life in industrial environments
• Secure, vibration-resistant fastening thanks to the tri-lobe shank design that prevents loosening under dynamic loads
• Optimized for plastic assembly with a blunt tip and fully threaded No. 8 x 1/4" size, ensuring precise engagement without material damage
• Streamlined installation process using a standard No. 23 drill bit (0.154" diameter), reducing setup time and errors
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in regulated industries

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for plastic fastening applications, where traditional screws may cause material stress or failure. The thread forming (TRS) design with a tri-lobe shank displaces plastic material without cutting, creating strong, load-bearing threads that resist vibration and pull-out. The Torx Plus IP20 drive system delivers maximum torque transfer, preventing stripping and enabling consistent tightening in automated or manual assembly lines. Ideal for electronics enclosures, automotive trim, and consumer products, these screws provide a reliable, RoHS 3 and REACH compliant solution for demanding industrial environments where material integrity and fastener performance are critical.

Specification Summary & Compliance

This No. 8 x 1/4" screw features a right-hand thread with 16 TPI and fully threaded length, manufactured to precise dimensional standards for consistent performance. The zinc-plated steel material and Torx Plus T20 drive ensure durability and compatibility with industry tools. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms adherence to environmental and safety standards, making these screws suitable for global supply chains and regulated industries.
