Professional Applications & Engineering Value

These No. 0 x 3/16" TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications. The thread forming design eliminates the risk of plastic chipping and creates permanent, high-strength threads that resist loosening under vibration. The Tri-Lobe shank cross-section strategically displaces plastic material during installation, reducing hoop stress and preventing the cracking that often occurs with standard fasteners. Combined with the Torx Plus IP5 drive system, these zinc-plated steel screws deliver exceptional torque transfer efficiency, enabling higher installation speeds while minimizing driver bit wear. This makes them ideal for high-volume production environments where reliability and efficiency are critical for plastic fastening solutions.

Specification Summary & Compliance

These inch-system fasteners feature precision Class 2A thread tolerances with a 0.06" thread diameter and 42 TPI thread pitch. The TRS (Thread Rolling Screw) design follows industry-standard thread forming specifications for plastic applications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current international standards for hazardous substance restrictions. The fasteners are designed for use with standard No. 54 drill bits (0.055" diameter) to achieve optimal hole preparation for plastic assembly applications.
