Professional Applications & Engineering Value

This M4 brass set screw is engineered to address common industrial challenges such as component slippage and corrosion-induced failure. The headless, slotted design with a flat tip is ideal for securing collars, gears, and pulleys on shafts without interfering with adjacent parts. Made from RoHS compliant brass, it offers excellent resistance to rust and galvanic corrosion, making it suitable for electrical enclosures, marine equipment, and precision instruments. The Class 6g thread fit and coarse pitch ensure reliable engagement in high-vibration environments, reducing maintenance downtime and enhancing assembly integrity in metric-based engineering projects.

Specification Summary & Compliance

This set screw features an M4 x 0.7 mm coarse metric thread with Class 6g tolerance for precise fit. It meets DIN 551 and ISO 4766 standards for dimensional accuracy and is RoHS 3 (2015/863/EU) compliant with exemption 6(c) for lead in copper alloys, ensuring environmental and safety adherence. The right-hand thread direction and 5 mm length provide consistent performance in standardized assemblies.
