Professional Applications & Engineering Value

These M3.5 TRS tapping screws are specifically engineered for plastic assembly applications where traditional fastening methods often fail. The thread forming design displaces plastic material rather than cutting it, creating stronger threads that resist pull-out and vibration loosening. The zinc-plated steel construction provides essential corrosion protection while maintaining the necessary strength for plastic-to-plastic and plastic-to-metal joints. With a standard 90° countersink angle and flat head profile, these screws sit flush with surfaces, eliminating protrusions in consumer products, electronic enclosures, and automotive plastic components. The fully threaded M3.5 x 12mm configuration ensures maximum thread engagement in various plastic thicknesses, making them ideal for applications requiring reliable, vibration-resistant fastening in thermoplastics and other plastic materials common in manufacturing and assembly operations.

Specification Summary & Compliance

These metric TRS tapping screws feature M3.5 diameter with 12mm length and approximate 1.57mm thread pitch, designed for use with 2.6mm drill bits. The thread forming (Type TRS) right-hand threading follows standard metric specifications for plastic applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial compliance requirements for hazardous substance restrictions. The Phillips No. 2 drive system provides standardized installation compatibility across industrial tooling systems.
