No flames are needed, preventing the potential hazards of traditional heating methods and minimizing the impact on surrounding parts. No water cooling required, and operation does not need professional certification.

The bolt heater tool comes with multiple coils that easily handle irregular workpieces. Whether it's small screws or larger bearings, it provides precise heating. The purple copper conductive wire is more efficient, and the glass fiber insulation layer offers superior resistance to breakage.

The handheld design ensures a stable grip and more flexible operating angles. The built-in cooling fan helps guard heat-sensitive parts. The bright LED light at the end helps you work smoothly in the dark and serves as a reminder not to touch the coils.

Simply loosen the two side nuts on top to easily replace the coils. The induction bolt heater tool locks securely and is not easy to loosen.
