Professional Applications & Engineering Value
This M4 thumb screw combines the strength of 18-8 stainless steel with the user-friendly acetal plastic head to address common assembly challenges. The knurled texture ensures a firm grip, reducing slippage during manual tightening in electronics, machinery, and fixtures. Its low-profile design prevents interference in compact setups, while the fully threaded metric coarse pitch accelerates installation and resists loosening under vibration. Ideal for industrial applications requiring quick access and durability, this screw supports maintenance efficiency and reduces tool dependency, enhancing productivity in environments like control panels, enclosures, and prototyping.
Specification Summary & Compliance
This thumb screw adheres to metric thread standards with M4 x 0.7mm coarse pitch and Class 4g6g thread fit for precise dimensional accuracy. It is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restricted substance-free components. The specifications include a right-hand thread direction, 12mm length, and full threading for consistent performance in regulated industries.
