Professional Applications & Engineering Value

This M4 x 0.7mm coarse thread screw is engineered to address common industrial challenges such as material fatigue and assembly efficiency. The zinc-plated steel offers a robust barrier against corrosion, which is critical in environments exposed to moisture or chemicals. The slotted cheese head design not only facilitates straightforward installation but also provides a low-profile finish, making it ideal for applications where space is limited. With its fully threaded metric body and Class 6g fit, it ensures a precise and secure fit in pre-tapped holes or nuts, minimizing the risk of cross-threading and enhancing joint integrity. These characteristics make it a reliable choice for securing components in machinery, automotive assemblies, and electronic enclosures, where consistent performance and regulatory compliance are paramount.

Specification Summary & Compliance

This screw adheres to precise dimensional standards with a M4 thread size, 0.7mm coarse pitch, and 6mm length, ensuring compatibility with metric components. The threading conforms to a Class 6g fit per ISO/metric standards, providing reliable tolerance control. Manufacturing and material specifications meet DIN 920, guaranteeing consistent quality and performance. Furthermore, the product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for use in various industrial and consumer applications without hazardous substances.
