Professional Applications & Engineering Value
This M4 flat head Torx screw is engineered to address critical industrial challenges, such as vibration loosening and corrosion-induced failure. The combination of 18-8 stainless steel and a passivated finish provides exceptional resistance to moisture and chemicals, making it ideal for outdoor equipment, machinery assemblies, and electronic enclosures. The T20 Torx drive offers superior torque control compared to traditional drives, reducing the risk of head stripping during high-torque applications. With a coarse metric thread and fully threaded design, it ensures rapid installation and robust performance in soft materials like plastics or wood, where precise thread engagement is crucial. This screw delivers consistent, reliable fastening in demanding environments, minimizing maintenance and downtime.
Specification Summary & Compliance
This screw features a metric M4 x 0.7mm coarse thread with Class 6g tolerance for precise fit, a right-hand thread direction, and a fully threaded 20mm length. It complies with ISO 14581 manufacturing specifications and is verified to be RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to international environmental and safety standards.
