Professional Applications & Engineering Value
Engineered for precision and durability, these M4 metric screws with T20 Torx drive address critical industrial challenges such as fastener stripping and corrosion-induced failure. The 18-8 stainless steel material, enhanced by a passivated finish, provides exceptional resistance to rust and chemicals, making them ideal for outdoor equipment, machinery assemblies, and electronic enclosures exposed to moisture or aggressive agents. The fully threaded design and coarse pitch ensure rapid installation and robust holding power in metals and plastics, while the rounded head reduces snagging risks in automated production lines. By conforming to ISO 7380, these screws deliver consistent dimensional accuracy, simplifying inventory management and reducing downtime in maintenance-heavy sectors like automotive and aerospace.
Specification Summary & Compliance
This product adheres to precise dimensional tolerances, including Class 6g thread fit per metric standards and a coarse thread pitch of 0.7mm. Manufacturing follows ISO 7380 specifications for rounded head screws, ensuring interoperability with certified components. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms the absence of hazardous substances, supporting sustainable and safe industrial operations.
