The ETBB06 is an offset tungsten bucking bar, stepped so you can clear a lip or edge and still seat flat against the rivet tail. It measures 2.5 inches long by 1.25 inches wide by 1 inch thick and weighs 1.65 lbs. It is a versatile everyday size for general airframe and sheet metal riveting.

The density of tungsten packs heavy backing force into a smaller body than an equivalent steel bar, without the extra bulk. In a cramped bay that means less bar to hold and position, a steadier rebound behind the rivet set, and less hand and wrist fatigue over a long session.

Made in the United States from high density tungsten, each bar is finished to protect the panels you set rivets against. It is a dependable pick for aircraft assembly and repair, restoration and experimental builds, and any solid rivet work where control and access matter.

To be sure this is the right bar for your rivet pattern, USA Tungsten publishes this bar’s detailed measurements and photos, and the guide to bucking bar shapes can help you compare it against other sizes and shapes.
