Copper nails are used with matching copper roves to form a copper rivet. These nails are extremely robust, easy to drive and when the wood fibers become damp and swell, will never work loose. Copper roves are slightly conical washers. A copper nail is hammered through the joint, a rove is pushed over the end (concave side inward) and the nail is peened over to form a copper rivet.
