Strut channel nuts are used to place and secure fittings, electrical panels, junction boxes, or piping clamps within channels or conduits. They consist of a nut with grooves on the side that fit over side of the channel edge and a screw hole. Tightening a screw in the nut causes teeth in the grooves to lock into the channel edge, holding the nut in place.
Channel Nut Thread Size: 1/4" - 20 to 7/8" - 9 plating zinc.
