Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws deliver exceptional engineering value in plastic assembly applications where reliable fastening is critical. The thread forming technology eliminates the need for pre-tapped holes, creating strong mating threads directly in plastic substrates without creating chips or debris. This makes them ideal for electronic enclosures, automotive plastic components, and industrial equipment housings where clean installation is essential. The tri-lobe shank cross-section reduces driving torque by up to 30% compared to standard fasteners, preventing material stress and cracking while maintaining superior pull-out resistance. The external hex drive provides positive engagement with standard tools, ensuring consistent installation torque and reducing the risk of fastener damage during assembly operations.

Specification Summary & Compliance

This No. 12 thread forming screw features a 0.216" thread diameter with 11 threads per inch and 1-1/2" fully threaded length.
