Professional Applications & Engineering Value
These M4 thread forming screws are specifically engineered for plastic assembly applications, where traditional fastening methods often lead to material stress or failure. The TRS (Thread Rolling Screw) design with a blunt tip and fully threaded shank displaces plastic material during installation, creating precise internal threads that resist vibration loosening and provide exceptional pull-out strength. Made from 18-8 stainless steel, they maintain integrity in humid or corrosive environments common in automotive electronics, consumer appliances, and outdoor equipment. The Phillips pan head with No. 1 drive ensures quick installation with standard tools, reducing assembly time while the rounded profile minimizes snagging risks in finished products.
Specification Summary & Compliance
These metric thread forming screws feature M4 diameter with 16mm length and 1.79mm thread pitch, manufactured to standard TRS specifications for plastic applications. The fully threaded design with blunt tip ensures consistent performance across various plastic materials. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming they are free from restricted substances and suitable for global industrial use.
