Professional Applications & Engineering Value

This black Acetal Plastic thumb nut solves critical assembly challenges where metal fasteners would corrode or require excessive maintenance. The 10-24 UNC coarse thread design provides excellent engagement in plastic components and soft materials, while the knurled grip enables rapid hand-tightening in confined spaces or high-volume production environments. Engineered for industrial applications requiring frequent adjustments, the Acetal material maintains dimensional stability across the specified temperature range, preventing loosening from thermal expansion. The fully threaded right-hand configuration ensures maximum thread contact for vibration resistance in machinery, enclosures, and electrical assemblies where tool-free access is essential.

Specification Summary & Compliance

This thumb nut features Class 2B thread fit per UNC standards with precise dimensional control including 5/8" head diameter, 31/64" collar diameter, and 19/64" height. Manufactured to inch system measurements with standard round profile and coarse thread spacing. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for regulated industries and international markets.
