Professional Applications & Engineering Value
These M4 x 20mm zinc-plated steel TRS tapping screws are engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The thread forming action creates strong, permanent threads in plastics without generating chips, reducing the risk of failure in vibration-prone applications. With a Phillips drive and blunt tip, they ensure controlled insertion and high clamp force, ideal for electronics enclosures, automotive trim, and consumer products. The fully threaded design and pan head provide uniform pressure distribution, enhancing durability in repetitive industrial use while meeting strict RoHS and REACH compliance for safe, reliable fastening solutions.
Specification Summary & Compliance
This M4 metric screw features a 20mm length with fully threaded design and approximate 1.79mm thread pitch, adhering to standard thread forming tolerances for precise fit. The zinc-plated steel material ensures consistent performance, and the product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for industrial and commercial applications requiring environmental safety and durability.
