Professional Applications & Engineering Value

This M10 thumb screw is engineered to address common challenges in machinery, electronics, and equipment assembly where frequent adjustments or tool-less access is required. The black-oxide steel material provides excellent wear and corrosion resistance, extending service life in humid or abrasive conditions. Its four-arm head design in zinc-plated cast iron offers a comfortable, non-slip surface for hand-tightening, reducing installation time and minimizing the risk of damage from tools. The fully threaded body and coarse thread spacing enable rapid installation and reliable clamping force, while the extended tip aids in aligning components accurately. Ideal for industrial enclosures, jigs, and prototypes, this screw combines high tensile strength and precision thread fit to prevent loosening under vibration, ensuring stable performance in dynamic applications.

Specification Summary & Compliance

This thumb screw adheres to metric threading standards with M10x1.5 mm coarse threads and a Class 6g thread fit for consistent dimensional accuracy. It is manufactured to meet RoHS 3 (2015/863/EU) compliance with exemption 6(a)-I and REACH (EC 1907/2006) standards, ensuring it is free of hazardous substances for safe use in various industrial sectors. Key specifications include a right-hand thread direction, fully threaded shank, and a collar diameter of 19 mm for added stability.
