Channel Nuts allow contractors to securely place a fitting, junction box, electrical panel, or pipe clamp in a precise location along the entire length of the channel. Channel Nuts are vital to the channel support system. They are inserted through the open side of the channel then rotated through 90 Degree where their toothed grooves fit against the return flange of the channel. The sprung versions will hold themselves in position as opposed to the plain channel nuts are pre-mounted on any bolt prior to insertion. They are available in M6, M8, M10, M12 & M16 tapped holes.
