Key Features & Benefits at a Glance
- Superior torque transmission with Torx Plus IP25 drive, reducing cam-out and tool wear for reliable installation
- Excellent corrosion resistance from zinc-plated steel, ensuring long-term durability in various environments
- Secure fastening in plastic materials due to the tri-lobe shank design that prevents loosening under vibration
- High thread engagement with 14 TPI fully threaded design, providing maximum holding power in plastic assemblies
- Easy installation without pre-drilling as thread forming TRS type creates strong threads in plastic substrates
- Wide compatibility with standard No. 15 drill bits (0.18" diameter) for simplified assembly processes
- Environmental compliance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing
Professional Applications & Engineering Value
These No. 10 zinc-plated steel TRS tapping screws are specifically engineered for plastic assembly applications where vibration resistance and pull-out strength are critical. The thread forming design displaces material rather than removing it, creating stronger threads that won't strip under stress. The tri-lobe shank cross-section provides anti-rotation properties, making these Torx Plus driven screws ideal for automotive trim, electronic enclosures, and consumer products where reliable fastening is essential. With fully threaded construction and blunt tip design, they ensure consistent performance across various plastic densities without cracking or splitting the substrate.
Specification Summary & Compliance
These tapping screws feature a No. 10 thread diameter (0.19") with 14 threads per inch and 3/4" length, manufactured to precise dimensional standards. The TRS thread forming type and tri-lobe shank provide secure fastening in plastic materials without requiring tapped holes. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industry standards for hazardous substance restrictions.
