A safe and fast way to loosen a rusted or corroded suspension bolt with induction heat

Removing a rusted, corroded, or locked suspension bolt is often a lengthy, difficult and frustrating task, especially if using a ratchet wrench. It usually requires the application of penetrating fluid, or blasting the area with a torch – this is time consuming, can cause unwanted damage and it’s a potential risk to your safety.

However, help is at hand. The Mini-Ductor® Venom™ handheld induction heating tool heats metal parts in seconds using invisible, flameless heat.

This allows all types of adhesives bonded to metal, fasteners bonded with thread lock compound, and seized hardware to be removed and released much quicker and safer than by traditional naked flame heating.

Using a torch leads to heat being blown away from the load, wasting its energy and transferring its heat to unwanted areas. With the Mini-Ductor® Venom™ nearly all the energy pulled is applied to the load, using invisible heat, making the tool faster and more energy efficient.

Mechanics do not need to run the risk of using a torch which could damage the rubber ball joint, or the surrounding area.

The Mini-Ductor® coils come in different diameters to suit different nut sizes. Induction heating provides a safer, quicker and less damaging alternative to naked flame heating and a great return on investment. Apart from the increased safety benefits, the use of the Venom™ can increase a garage’s part removal and repair productivity by over 50%.
