Professional Applications & Engineering Value

This M4 brass set screw is engineered to address common industrial challenges such as corrosion in humid or chemical-exposed settings, thanks to its brass material that naturally resists rust and degradation. The headless design with a slotted drive allows for flush mounting in tight spaces, preventing protrusion and ensuring a clean finish. With a right-hand metric thread and coarse pitch, it offers quick assembly and reliable grip in components like machinery, electronics, and automotive parts, reducing maintenance downtime. The flat tip applies even pressure, safeguarding sensitive surfaces from indentation. Ideal for precision set screw applications requiring adherence to DIN 551 and ISO 4766 standards, it delivers consistent performance in demanding engineering environments.

Specification Summary & Compliance

This set screw features a metric M4 thread size with a 0.7 mm coarse pitch and Class 6g thread fit for precise dimensional accuracy as per ISO standards. It complies with DIN 551 and ISO 4766 specifications for manufacturing consistency and is RoHS 3 (2015/863/EU) compliant under exemption 6(c) for lead in copper alloys, ensuring environmental safety without compromising mechanical integrity.
