Easily press into self-retaining positions in center-panel locations or over panel edges through the rectangular hole. Prevents screws from coming loose due to vibration and locks against mating surface for greater stability and durability. Recommended for hard-to-reach or blind installations where threaded nut tightening would not be used. Does not include full bearing surface on lower leg. Black Phosphate Finish provides added protection and resistance. Comes in package quantities of 1,000, 2,000 and 3,000. Dimensions vary per model.
