Professional Applications & Engineering Value

This M3 set screw is engineered to address common challenges in precision assembly, such as component slippage and corrosion-induced failure. The brass material provides inherent resistance to rust and galvanic corrosion, making it ideal for electrical enclosures, marine equipment, and plumbing systems where moisture exposure is a concern. With its headless, slotted design and flat tip, it ensures secure fastening of gears, pulleys, and collars onto shafts without protruding, reducing the risk of interference in compact machinery. The Class 6g thread fit and coarse pitch offer reliable holding power against vibrations, common in automotive and automation applications. Manufactured to DIN 551/ISO 4766 standards, these screws deliver consistent performance, supporting efficient maintenance and reducing downtime in industrial settings.

Specification Summary & Compliance

This set screw features an M3 x 0.5 mm coarse pitch with Class 6g thread tolerance for precise fit, and an 8 mm length with a flat tip. It conforms to DIN 551 (equivalent to ISO 4766) for dimensional accuracy and manufacturing consistency. The product is RoHS 3 (2015/863/EU) compliant under exemption 6(c) for lead in copper alloys, ensuring adherence to environmental and safety regulations in industrial fastener applications.
