Professional Applications & Engineering Value

This 5/16"-18 UNC thumb nut delivers exceptional value in applications requiring frequent adjustments or tool-free operation. The Acetal Plastic material offers low friction and high stiffness, preventing galling and reducing wear in dynamic assemblies. Its knurled head ensures a firm grip even with oily hands, addressing slippage issues in maintenance-heavy environments like conveyor systems, packaging machinery, and electronic enclosures. The coarse thread design resists vibration loosening, while the Class 2B thread fit maintains precise alignment, making it ideal for prototyping, fixtures, and equipment where rapid access is critical without compromising mechanical integrity.

Specification Summary & Compliance

This thumb nut adheres to UNC thread standards with Class 2B thread fit for consistent dimensional accuracy. It features a round head shape with 1" diameter, 41/64" collar diameter, and 27/64" height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
