Professional Applications & Engineering Value

This flanged thumb nut is engineered to solve critical challenges in industrial maintenance, machinery, and equipment assembly where tool access is limited or speed is essential. The passivated 18-8 stainless steel construction resists oxidation and chemical exposure, making it ideal for outdoor, marine, or washdown environments. The coarse UNC thread and Class 2B fit enable rapid installation with minimal cross-threading risk, while the knurled round head provides a non-slip surface for secure manual tightening. Its flanged profile increases the bearing surface, reducing surface pressure and helping to prevent loosening under vibration, offering a reliable, tool-free fastening solution for panels, access covers, and adjustable components.

Specification Summary & Compliance

This thumb nut features 7/16"-14 UNC coarse threads with a Class 2B thread fit for consistent engagement and right-hand thread direction. Manufacturing adheres to standard inch system dimensions, including a collar diameter of 11/16" and a head diameter of 1". The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
