Galvanised Cup Head Bolts

    Also called a carriage or coach bolt, the galvanised cup head bolt bears a round head that sits on top of a square, designed to hold the head in place when tightened. The threaded shank is driven through a pre-drilled hole and secured in place by the nut. Galvanised coating makes it ideal for outdoor jobs and for use with treated timbers. Other uses include fastening timber frames, fencing, furniture and retaining walls.
