Professional Applications & Engineering Value

This M3 brass set screw addresses critical engineering challenges in precision assembly applications. The headless design with slotted drive eliminates protrusions in machinery where clearance is limited, while the Class 6g thread fit maintains tight tolerances against loosening under vibration. The brass construction provides excellent corrosion resistance in moist or chemical environments where steel fasteners would degrade. Particularly valuable in precision instruments, electrical enclosures, and rotating machinery, the flat tip design ensures positive seating on shafts and collars without damaging surfaces. Meeting DIN 551 and ISO 4766 standards, these metric set screws deliver reliable performance in both European and international manufacturing applications requiring standardized components.

Specification Summary & Compliance

This precision M3 x 0.5 mm coarse pitch set screw features Class 6g thread tolerance according to metric standards, ensuring proper fit with mating components. Manufacturing conforms to DIN 551 specifications (equivalent to ISO 4766) for dimensional accuracy and quality assurance. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloys, meeting environmental regulations for industrial use. The right-hand thread direction and 6mm length provide standardized installation across various applications requiring secure fastening solutions.
