Leo Bolts Polished Stainless Steel Hex Weld Nuts, For Hardware Fitting, Size : Standard

Hex nuts are the most common six-sided fasteners with internal threads, screwing on to the shank of a bolt or a hex cap screw. Machine screw nuts are hex nuts that are designed to mate with machine screws, generally used in metal fastening. Left hand hex nuts feature reversed threads, so tightening is accomplished by spinning counterclockwise. Panel hex nuts are thinner, low-profile nuts used in small, confined spaces.
