Professional Applications & Engineering Value

This M2.5 brass set screw with 0.45 mm coarse pitch thread addresses critical engineering challenges in precision assembly applications. The brass construction provides excellent corrosion resistance in electrical components, marine environments, and plumbing systems where galvanic corrosion is a concern. The Class 6g thread fit ensures reliable engagement in threaded holes while accommodating minor manufacturing variations. The headless design with slotted drive enables flush mounting in rotating machinery, precision instruments, and electronic enclosures where protruding fasteners would interfere with operation. The flat tip design creates superior clamping force without damaging shaft surfaces, making it ideal for positioning collars, gears, and pulleys in mechanical drive systems. These metric set screws are particularly valuable in applications requiring repeated adjustments while maintaining positional accuracy.

Specification Summary & Compliance

This precision M2.5 set screw features a 0.45 mm pitch coarse thread with Class 6g tolerance according to ISO metric standards. The fastener is manufactured to DIN 551 specifications where identical to ISO 4766, ensuring dimensional consistency and mechanical performance. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloys, meeting environmental regulations while maintaining the material properties required for reliable industrial fastening applications. The right-hand thread direction and 5 mm length provide standardized compatibility across metric-based engineering designs.
