 Induction Bolt Heating

Expanding bolts with induction is the proven timeand labor-saving alternative to ineffi cient flame and resistance heating. With induction, a specially designed coil is inserted into the bolt. Rapid, precisely controlled and localized heat is then induced directly in the bolt. The heat expands the bolt by an exact, pre-decided length, making it easy to remove the nut.The speed and accuracy of induction heating prevents damage to the bolt threads. The heating process is so quick there simply isn’t enough time for heat to travel into the thread area. And of course, with induction there’s no risk of rods melting inside the bolts—a common and time-consuming problem with alternative heating methods.
