Professional Applications & Engineering Value

This M16 thumb nut is engineered to solve critical assembly challenges in maintenance-heavy and corrosive environments. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, making it perfect for outdoor equipment, food processing machinery, and marine applications where durability is paramount. The fully knurled head offers an exceptional grip, allowing operators to apply significant torque by hand without specialized tools, which speeds up assembly and disassembly processes. Its metric coarse threading (M16x2 mm) and Class 6H thread fit ensure a secure, vibration-resistant connection on shafts, axles, and adjustment rods, reducing the risk of loosening under dynamic loads. This industrial thumb nut delivers reliable performance where tool access is limited and manual adjustment is frequent.

Specification Summary & Compliance

This thumb nut features M16x2 mm metric coarse threads with a Class 6H thread fit for precise dimensional accuracy and reliable engagement. It is manufactured from 18-8 Stainless Steel and includes a fully threaded, right-hand design. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) standards, ensuring it meets stringent environmental and safety regulations for industrial use.
