Release corroded fasteners on the exhaust, suspension, driveline and chassis without tearing out the stud or damaging the thread.
Professional induction heaters
Induction bolt heater for seized bolts, nuts and screws
Heat a seized bolt, nut or screw in seconds, without a flame. The induction heater that garages, workshops and maintenance teams reach for every day: precise, powerful and safe for everything around the part.
Flameless, targeted heating
A tool that heats the fastener, not everything around it
An induction bolt heater generates an alternating magnetic field. A steel bolt, nut, screw or stud inside that field heats directly and expands: the rust gives way, the thread releases and the fastener turns out without brute force and without snapping.
Wiring, hoses, seals and paint stay out of the heat. Release the trigger and heating stops. That is all there is to it — on the exhaust, the suspension, the driveline or the chassis.
- Seized or rusted bolts, nuts, screws, studs and threads
- Bearings, bushings, hubs and other press-fitted steel parts
- No open flame: heating stops the moment you release the trigger
- Interchangeable coils for every diameter and every access
Induction heating in practice
A few seconds is all it takes
Slide the coil over the nut or around the bolt, press the trigger and watch the fastener take colour. A standard nut is hot in seconds; a truck chassis bolt takes little longer with a W2300 Power+. The closer the coil fits the part, the faster the heat arrives.
Coils change in one movement: one size per diameter, a flexible coil for bulky parts, a U-coil for awkward access. You work under the lift, in the engine bay or at the bench with the same tool.
One heating method, many workshop jobs
A high-strength thread-locker lets go from around 250 °C. Heat the screw for a few seconds and it turns out by hand, without forcing the drive.
Heat bearings, bushings, hubs and housings under control for a clean removal. See our guide to the induction bearing heater.
Why workshops replace the torch with an induction bolt heater
Heat next to a fuel tank, a wiring loom or a brake hose without heat shields or an extinguisher at hand. Nothing burns, nothing melts.
A torch heats everything it touches; induction heats only the steel of the fastener. The aluminium housing, the paint and the seals stay cold.
No gas bottles, no hot-work permit, no set-up time: plug in, pick a coil and heat. A cleaner, safer bay, day after day.

Choose the output and kit for your workload
All three systems heat by induction. They differ in output, in the size of fastener they handle every day and in the coil range supplied with the kit you choose.
| System | Best suited to | Output | Available kits |
|---|---|---|---|
| iDuctor W1200 | Everyday automotive bolts, nuts and screws, precise daily work | 1200 W | Basic and Professional |
| iDuctor W2000 120V | Heavier workshop work on a 120-volt supply | 2000 W | Basic and Professional |
| iDuctor W2300 Power+ | Truck bolts, massive parts and intensive use | 2300 W | Basic and Professional |

2300W Power+
iDuctor W2300 Power+ Kit
The iDuctor W2300 Power+ Kit is a high-output induction heating kit for heavier jobs. With 2300 watts of output, it safely loosens larger and heavier ferrous parts without an open flame and supports Flexcoils from 1100 mm up to 3500 mm.
How much does an induction bolt heater cost?
Every system comes as a Basic Kit and a Professional Kit, the latter with a complete coil set. The price excluding and including VAT, the kit contents and free shipping are on each product page: click here to see prices.
A cheap bolt heater is judged in use: real output, coils available for every diameter, warranty and spare parts. The iDuctor is covered by a 12-month warranty, backed by a European dealer network and by coils sold separately to replace or extend your set. One exhaust stud freed without breaking it and without a torch, and the tool has already started paying for itself.
About the induction bolt heater
What materials can induction heat?
All ferromagnetic metals: steel, cast iron, magnetic stainless. That covers practically every bolt, nut, screw, stud and bearing. Aluminium and copper do not heat directly — which is exactly the advantage: the housing stays cold while the fastener heats.
Can I heat a bolt without damaging the parts around it?
Yes, that is the whole point of induction. Only the steel inside the coil heats; hoses, wiring, seals and paint see no flame at all. Just check what sits closest before you start, as with any job. Our step-by-step guide: Loosen seized bolts without a torch.
Can I heat a screw or a nut, not just a bolt?
Yes. An induction bolt heater heats any steel fastener: hex or socket-head screws, nuts, studs, threaded rod. For a nut the coil slides over the top; for a screw it surrounds the head or the exposed shank. Screws glued with thread-locker release after a few seconds of heat.
Which output do I need for the bolts in my workshop?
The W1200 covers everyday automotive fasteners and precise daily work. The W2000 120V is the choice for a 120-volt supply. The W2300 Power+ heats truck bolts and massive parts and stands up to intensive use. Our selector: Which iDuctor do I need?
Induction or torch: what is the difference in the workshop?
Induction heats the fastener from the inside, without a flame, in seconds and without touching what surrounds it. A torch heats everything in front of it and brings its own constraints: gas bottles, hot-work permits, an extinguisher, scorched paint. Compare both methods point by point: Induction heater vs gas torch.
