Tungsten bucking bars
New to choosing a bar? See how to choose a bucking bar and bucking bar shapes explained, compare every bar on the size and weight chart, match a competitor part on the cross-reference, or get a recommendation from the Bucking Bar Selector.
A tungsten bucking bar is a dense backing tool that absorbs a rivet gun’s force so the shop head of a solid rivet forms cleanly. Because tungsten is roughly 2.5× denser than steel, a tungsten bar packs the same bucking mass into a noticeably smaller block, meaning tighter access, less hand fatigue, and cleaner driven heads. This catalog lists 51 tungsten bucking bars, organized by shape, weight class, and access type. Not sure which fits your rivet location? Use the Bucking Bar Selector or request a quote on any SKU.
