Professional Applications & Engineering Value

These Black-Oxide Steel TRS thread forming screws deliver exceptional engineering value in plastic assembly applications where material integrity is paramount. The Tri-Lobe shank design and thread forming technology eliminate the need for pre-tapped holes while creating strong, vibration-resistant connections that won't loosen over time. The T8 Torx drive system provides superior torque transmission compared to traditional drives, reducing installation time and preventing fastener damage. Particularly valuable in plastic fastening applications across automotive, electronics, and consumer goods manufacturing, these screws maintain consistent clamping force without stressing or cracking delicate plastic components. The fully threaded design with 28 TPI precision ensures maximum thread engagement and pull-out resistance in various plastic densities.

Specification Summary & Compliance

This No. 2 x 3/8" plastic tapping screw features inch system measurements with precision right-hand threading at 28 TPI and 0.086" thread diameter. The TRS thread forming design creates strong, permanent threads in plastic substrates without chips or debris. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use in global industrial applications. The combination of Black-Oxide Steel construction, Torx T8 drive, and Tri-Lobe shank geometry delivers reliable performance meeting industrial fastening requirements for plastic assemblies.
