Professional Applications & Engineering Value

These M2.2 tapping screws are specifically engineered for plastic assembly applications where reliable fastening is critical. The TRS thread-forming design eliminates the need for separate tapping operations by displacing plastic material to create strong, vibration-resistant threads. Made from 18-8 stainless steel, these screws provide excellent corrosion resistance that prevents degradation in outdoor applications or harsh environments. The Phillips pan head configuration combines easy installation with a low-profile appearance, making them ideal for consumer electronics, automotive trim components, and industrial equipment where both aesthetics and performance matter. The fully threaded design with 0.98mm pitch ensures maximum engagement in plastic substrates, preventing pull-out and maintaining structural integrity under dynamic loads.

Specification Summary & Compliance

These metric M2.2 x 4mm tapping screws feature standard thread tolerances for plastic applications with fully threaded configuration and 0.98mm pitch. The TRS thread-forming type is manufactured to industry standards for plastic fastening applications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest restrictions on hazardous substances for industrial use.
