Hex nuts, Stainless steel 18-8 - Left hand (reverse) thread

Nut

Nut size (A.K.A. diameter) is the size bolt that the nut is used with. The same is true of the thread count. Thus a 1/4"-20 nut fits a 1/4"-20 bolt.

Note: Left hand (reverse) thread nuts. These nuts will not work with standard bolts. See our nuts page for standard nuts.
