S-99512A117 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread retention in plastics through TRS thread forming design that creates strong, permanent threads without chips
• Enhanced corrosion resistance with zinc-plated steel construction for extended service life in industrial environments
• Maximum torque transfer and reduced cam-out with Torx Plus IP5 drive system for secure installation and removal
• Excellent holding power with 42 threads per inch and Tri-Lobe shank design that prevents loosening under vibration
• Optimized for plastic applications with blunt tip and fully threaded design for smooth material penetration
• Reliable dimensional consistency with precise No. 0 screw size and 3/8" length for uniform performance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications where traditional fasteners often fail. The thread forming design eliminates the risk of material cracking or stress concentration by displacing rather than removing plastic material, creating stronger threaded connections. The Tri-Lobe shank cross-section provides exceptional resistance to vibrational loosening, while the Torx Plus T5 drive system ensures maximum torque transmission without stripping during installation. This combination makes these industrial fasteners ideal for electronics enclosures, automotive plastic components, and consumer products where reliable, long-term fastening in plastic substrates is critical.

Specification Summary & Compliance

These TRS tapping screws feature precise inch system dimensions including 0.06" thread diameter, 3/8" length, and 42 threads per inch with standard thread tolerances. The thread forming screws utilize TRS (Thread Rolling Screw) tapping method with right-hand threading and are manufactured to industry standards for plastic fastening applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures they meet the latest international environmental and safety standards for industrial use.
