Professional Applications & Engineering Value

This Nylon 6/6 plastic thumb nut delivers exceptional value in applications requiring frequent adjustments or tool-free maintenance. The wing-style design with 1 3/8" width provides substantial leverage for hand-tightening operations, significantly reducing assembly time in electrical enclosures, machinery guards, and laboratory equipment. The chemical-resistant properties of Nylon 6/6 make it ideal for environments exposed to oils, solvents, and moisture, while its non-conductive characteristics prevent electrical shorts. The 5/16"-18 UNC coarse threads with Class 2B fit ensure reliable engagement with mating components, maintaining secure fastening even after repeated adjustments. This combination of material durability and ergonomic design solves critical challenges in maintenance-heavy industrial settings where corrosion resistance and quick access are paramount.

Specification Summary & Compliance

This thumb nut features precision 5/16"-18 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring consistent dimensional accuracy and reliable performance. The right-hand thread direction follows conventional tightening practices. Manufacturing complies with RoHS 3 (2015/863/EU) environmental regulations, guaranteeing restriction of hazardous substances. Critical dimensions include 41/64" base diameter, 1 3/8" width across wings, and 3/4" height, maintaining the standard wing nut profile for universal compatibility.
