Professional Applications & Engineering Value

This M8 brass set screw delivers exceptional engineering value through its specialized headless configuration and Class 6g thread fit, specifically engineered for precision alignment and securing applications. The 1.25mm coarse pitch metric thread provides superior engagement in both metallic and non-metallic components, while the flat tip design ensures maximum contact surface for secure component positioning without marring surfaces. Manufactured from corrosion-resistant brass material, this fastener excels in electrical applications, marine environments, and plumbing systems where galvanic corrosion must be prevented. The slotted drive style offers reliable tool engagement for maintenance and adjustment operations, making it ideal for machinery alignment, gear positioning, and precision instrument assembly where vibration resistance and dimensional stability are critical performance requirements.

Specification Summary & Compliance

This precision metric set screw features M8 x 1.25mm coarse thread spacing with Class 6g thread fit tolerance per ISO standards, ensuring dimensional accuracy across production batches. The 20mm length with flat tip type and right-hand thread direction conforms to DIN 551/ISO 4766 manufacturing specifications. Compliance with RoHS 3 (2015/863/EU) regulations under exemption 6(c) for lead in copper alloy confirms environmental responsibility while maintaining mechanical performance requirements for industrial applications.
