The Chief Heavy Duty Rivet Gun puts out nearly twice the force of the company’s standard rivet gun, enabling collision repair technicians to use it to install rivets in even the strongest steels, including Usibor. Approved by Mercedes-Benz, the Heavy Duty Rivet Gun offers a compression force of 22,000 lbs. The tool includes a retract feature and a dial to adjust the output working pressure. The dial provides infinite adjustment of the working pressure so the output force can be controlled to the desired level. The Heavy Duty Rivet Gun can be used to install self-piercing or flow form rivets and to punch holes.
