Stick of fasteners

Abstract

An improved driving element, fastener placement system, method of fastening and combination of fastened workpieces are disclosed which include a generally U-shaped, staple-like fastener having a pair of legs spaced from each other by a crown which transversely extends between the upper ends of the legs to connect the legs to each other adjacent their upper ends and space the upper ends of the legs apart by a given distance. Each of the legs also has an opposite lower end which enter the respective workpieces which are to be fastened together. The fastener is positioned with the lower end of one leg in contact with one of the workpieces and the lower end of the other leg in contact with the other workpiece, and the fastener is then forcibly driven into the respective workpieces by a driving element which acts upon the crown in a manner to attempt or tend to shorten the distance between the upper ends of the legs by bending the crown and countersinking the legs and/or crown into the workpieces. This results in continuing forces which tend to continue to urge the respective workpieces together after the fastener has been driven.
