• Precise and secure fastening achieved with a fully threaded M3 x 0.5 mm coarse thread and Class 6g fit, providing consistent engagement and vibration resistance.
• Streamlined assembly and maintenance facilitated by the right-hand thread direction, conforming to standard metric practices.
• Compliance with global environmental standards, being RoHS 3 and REACH compliant, for use in regulated markets and sensitive applications.

Professional Applications & Engineering Value

This M3 thumb screw is engineered to solve common assembly challenges where frequent adjustments or tool-less access is required. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it suitable for electronics enclosures, machinery panels, and outdoor equipment. The fully threaded design with a coarse thread pitch ensures quick installation and robust holding power, reducing the risk of cross-threading. The knurled head provides a secure grip even with gloved hands, enhancing operator efficiency in maintenance-heavy or space-constrained industrial applications. Its high tensile strength and precise Class 6g thread fit guarantee reliable performance in dynamic or vibrating environments, minimizing loosening over time.
