Professional Applications & Engineering Value
This M12 brass set screw addresses critical industrial fastening challenges where corrosion resistance and dimensional stability are paramount. The headless design with slotted drive provides reliable torque transmission while maintaining a low-profile installation, ideal for machinery components, electrical enclosures, and precision instruments. The coarse 1.75mm pitch metric thread ensures rapid assembly in high-volume production environments while the Class 6g thread fit maintains consistent clamping force under vibration and thermal cycling. Manufactured from durable brass alloy, this fastener prevents galvanic corrosion when used with dissimilar metals, extending service life in harsh operating conditions where moisture or chemicals are present.
Specification Summary & Compliance
This metric set screw features M12 x 1.75mm coarse right-hand threading with Class 6g tolerance per ISO standards. The 20mm length with flat tip configuration meets DIN 551/ISO 4766 specifications for dimensional accuracy and mechanical properties. Manufacturing complies with RoHS 3 (2015/863/EU) regulations under exemption 6(c) for lead in copper alloys, ensuring environmental compliance without compromising material performance.
