Professional Applications & Engineering Value

These TRS plastic tapping screws are specifically engineered to address common fastening challenges in plastic assembly applications. The tri-lobe shank cross-section and thread forming design create strong, permanent threads in plastic materials without the risk of material cracking or stress concentration that can occur with traditional fasteners. The black-oxide steel construction provides essential corrosion protection while maintaining the mechanical strength required for demanding industrial environments. The T30 Torx drive system ensures maximum torque transmission during installation, reducing the likelihood of driver slippage and damaged screw heads. These features combine to deliver reliable, vibration-resistant connections in plastic components across automotive, electronics, and consumer goods manufacturing sectors where consistent performance and material integrity are critical.

Specification Summary & Compliance

These precision-engineered fasteners feature a 1/4" thread diameter with 10 threads per inch and 3/4" length in fully threaded configuration. The TRS thread forming design follows industry standards for plastic fastening applications, while the standard pan head with 0.492" diameter ensures proper seating. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications with strict material restrictions.
