These bonding fasteners feature an impressively large 38mm base to enable a secure fixing to a variety of surfaces. The fastener has been formed from mild steel by welding a hex nut to the base plate.
In this version of this popular fastener, the nut is closed by the base plate. This prevents rods or screws from penetrating the nut and also stops any adhesives used on the base from fouling the threads of the nut.
