Hillman Black Phosphate Standard U Speed Nut #10

Description

Speed nuts act as both a lock washer and nut, and are designed for quick application and removal. U-Type Speed Nuts perform the same fastening functions as the J-Type, but are used where a full bearing surface on the lower leg is desired. they are self-retained in screw-receiving position to provide simple, rapid attachment of mating panels and cannot turn as the screw is driven.
