Learn how tungsten bucking bars work, how to pick the right one, and how weight and shape affect the job. Start with the basics or jump to the size and weight chart.
A tungsten bucking bar works by mass: a dense bar backs the tail of a solid rivet so the shop head forms cleanly in a smaller, easier-to-place tool than steel.
