ABSTRACT:
A clamp nail for joining two wood members tightly together by driving the nail endwise into the two members across the joint. The major length of the nail is in the form of a channel having a web and parallel upstanding flanges along both sides of the web. The web has at least two holes, leaving a central column member. The channel has a tapered transition section which may commence at the leading edge of the nail in the driving direction, or it may join a shorter channel portion at the leading edge, having a wider web and parallel upstanding flanges, to the major channel portion having a narrower web. The web is preferably bowed inwardly to bring the column member more nearly to the center of the flange height. The flange edges preferably are provided with a ledge configuration, the ledges being at a fixed distance from the back of the nail, whereby a plurality of like clamp nails may be stacked in making up a stick of clamp nails capable of use in a nailing machine having a magazine to receive a stick of said nails.
