Professional Applications & Engineering Value

This M3 rounded head slotted screw delivers exceptional engineering value in demanding applications where corrosion resistance and mechanical reliability are critical. Manufactured from 18-8 stainless steel with a passivated finish, it effectively resists oxidation and chemical exposure in industrial machinery, electrical enclosures, and outdoor equipment. The coarse metric thread (0.5mm pitch) and Class 6g tolerance enable quick assembly and vibration resistance, reducing maintenance intervals. Its fully threaded design and flat tip ensure maximum engagement in pre-tapped holes or with nuts, providing uniform clamping force. The narrow rounded cheese head with slotted drive offers a low-profile solution for spaces with limited clearance while maintaining tool compatibility. These features make it an ideal industrial fastener for automotive, electronics, and manufacturing sectors requiring durable, precision components.

Specification Summary & Compliance

This screw maintains Class 6g thread fit per ISO metric standards, ensuring dimensional accuracy and compatibility. It conforms to DIN 84 and ISO 1207 specifications for rounded head slotted screws, covering head dimensions, thread geometry, and mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant (including SVHC as of 01/17/2023), meeting stringent environmental and safety regulations for industrial use.
