Professional Applications & Engineering Value
This M8 thumb nut with 1.25 mm coarse thread pitch solves critical assembly challenges where tool access is limited or rapid adjustments are required. The zinc-plated steel construction provides essential corrosion protection for machinery, electrical enclosures, and outdoor equipment, while the standard wing nut profile delivers maximum torque transmission during hand-tightening operations. Engineers specify this metric wing nut for maintenance panels, adjustable fixtures, and temporary assemblies where its Class 6H thread fit maintains precise clamping force without loosening under vibration. The combination of right-hand thread orientation and coarse thread spacing makes it ideal for production lines requiring quick component changes without compromising thread integrity.
Specification Summary & Compliance
This thumb nut features M8 x 1.25 mm metric coarse threads with Class 6H thread fit per ISO standards, ensuring precise dimensional accuracy. The component maintains 12.7 mm base diameter and 36.5 mm width for consistent performance across applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to international environmental and safety standards for industrial components.
