Professional Applications & Engineering Value

This M5 flanged thumb nut is engineered to solve critical challenges in maintenance, assembly, and field service where tools are impractical. The passivated 18-8 stainless steel construction provides excellent resistance to rust and corrosion, making it ideal for outdoor equipment, food processing machinery, and marine applications. The knurled round head offers a secure, non-slip surface for quick manual tightening and adjustment, significantly reducing assembly time. The integrated flange acts as a built-in washer, distributing clamping force over a wider area to protect sensitive surfaces and prevent loosening under vibration. This combination of features delivers a robust, tool-free fastening solution that enhances operational efficiency and equipment reliability in demanding industrial environments.

Specification Summary & Compliance

This thumb nut features an M5 metric thread with a 0.8 mm coarse pitch and a Class 6H thread fit, ensuring high dimensional accuracy and reliable performance. The fastener is fully threaded with a right-hand thread direction. It is manufactured from Passivated 18-8 Stainless Steel and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming its suitability for regulated industrial and commercial applications.
