Professional Applications & Engineering Value

Engineered for precision assembly operations, these M4 metric screws with black oxide steel construction address critical industrial challenges including corrosion prevention and mechanical reliability. The fully threaded design with Class 6g thread fit ensures maximum thread contact in thin materials and soft substrates, while the extended tip significantly reduces cross-threading incidents during high-volume production. The narrow rounded cheese head profile provides optimal clearance in confined spaces commonly found in electronic enclosures, machinery panels, and automotive components. With coarse thread pitch (0.7mm), these fasteners deliver superior vibration resistance and maintain clamping force in dynamic loading conditions, making them ideal for manufacturing equipment, industrial controls, and transportation applications where durable metric fastening solutions are essential.

Specification Summary & Compliance

Manufactured to DIN 922 standards with Class 6g thread tolerance ensuring precise metric threading compatibility. The M4 x 0.7mm coarse thread configuration with 6mm length and fully threaded construction provides consistent performance across applications. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as steel alloying element and REACH (EC 1907/2006) regulations, meeting international environmental and safety requirements for industrial components.
