A knurled nut is a nut with a knurled outside surface, rather than hex. This makes them easy to tighten by hand, as well as adding a decorative finish. Knurled Thumb Nuts are used in finished materials, such as light fixtures, antique cars and motorcycles. 

Knurled Thumb Nuts are available in both Coarse (UNC) and Fine (UNF) thread sizes.
