An induction device for bolts is a specialized tool that uses induction heating to quickly and safely heat bolts, nuts, and other metal parts. The goal of the heating is to promote the expansion of the metal, thus making it easier to unblock stuck or rusted bolts and nuts. 

A major advantage of induction heating is that it focuses the heat directly on the metal part, without damaging the surrounding materials or components. It's also a safer and more efficient method compared to traditional heating techniques such as open flames or torches. Discover below the various induction heating devices.
