【NEWS】Tungsten Bucking Bar Craft

A bucking bar is a piece of steel used to upset the driven head of the rivet. Bucking bars are made in a variety of sizes to fit various situations. Bucking bars must be handled carefully to prevent marring surfaces. When choosing a bucking bar to get into small places,choose one in which the center of gravity falls as near as possible over the rivet shank. Avoid using too light of a bucking bar,because this causes excessive deflection of the material being riveted. And in turn, it might cause marking of the outer skin by the rivet set. A bucking bar that is too heavy will cause a flattened driven head and might cause a loose manufactured head.
