Professional Applications & Engineering Value
These zinc-plated steel TRS tapping screws are specifically engineered for plastic fastening applications where traditional fasteners often fail. The thread forming design eliminates the need for pre-tapped holes while creating strong, permanent threads in plastic substrates. The Tri-Lobe shank cross-section displaces material during installation, generating exceptional resistance to vibration loosening and back-out forces. With 20 threads per inch and right-hand threading, these screws provide reliable performance in plastic assembly operations across automotive, electronics, and consumer goods manufacturing. The blunt tip prevents material splitting, while the No. 2 Phillips drive ensures consistent installation torque for production efficiency.
