Professional Applications & Engineering Value
This zinc-plated brass flanged thumb nut is engineered for applications requiring frequent adjustments or tool-free assembly, such as in electrical enclosures, machinery guards, and instrumentation panels. The knurled round head provides a secure grip even with oily hands or gloves, reducing installation time and improving operator safety. Made from brass with zinc plating, it resists corrosion in demanding environments, while the flange design distributes clamping force evenly, minimizing surface damage and loosening from vibrations. The Class 6H metric coarse thread (M4 x 0.7 mm) ensures precise, reliable engagement with compatible bolts, making it ideal for maintenance, prototyping, and production lines where speed and durability are critical.
Specification Summary & Compliance
This thumb nut features a Class 6H thread fit per metric standards, with coarse threading (M4 x 0.7 mm) and right-hand direction for consistent performance. Dimensions include a 10 mm head diameter, 7 mm height, and 9 mm collar diameter. It is manufactured in compliance with RoHS 3 (2015/863/EU) with exemption 6(c) and REACH (EC 1907/2006), ensuring it meets environmental and safety regulations for industrial use.
