Professional Applications & Engineering Value
These M4 thread forming screws are specifically engineered for plastic assembly applications where traditional cutting screws may cause stress cracking or material failure. The TRS thread forming design displaces plastic material during installation, creating strong, load-bearing threads without generating chips that could interfere with sensitive components. Manufactured from 18-8 stainless steel, these fasteners maintain integrity in corrosive environments while the Phillips pan head provides a low-profile finish with excellent drive engagement. The fully threaded 35mm length and 1.79mm pitch ensure maximum thread engagement in various plastic thicknesses, making them ideal for electronics enclosures, automotive trim, and industrial equipment where vibration resistance and long-term reliability are critical.
Specification Summary & Compliance
This M4 x 35mm thread forming screw features metric dimensions with fully threaded TRS design and standard thread pitch of 1.79mm. The fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global manufacturing requirements. The Phillips No. 1 drive and pan head configuration provide reliable installation performance for industrial plastic fastening applications.
