Wielander & Schill Bolt heater – Accessory for I-Ductor Heat Inductor

Wielander & Schill Bolt Heater – Accessory for the I-Ductor Heat Inductor

The Wielander & Schill bolt heater is a purpose-built induction coil accessory that works with the I-Ductor heat inductor. It delivers concentrated induction heat directly to seized, corroded, or thread-locked bolts — so you can loosen them in seconds without using an open flame.

Why Use Induction Bolt Heating?

Seized bolts are one of the most common time-wasters in any bodyshop or workshop. For example, traditional methods such as oxy-acetylene torches create fire risks, damage surrounding plastics and wiring, and often round off bolt heads in the process. Consequently, what should be a quick removal turns into a lengthy, costly repair.

In contrast, the bolt heater accessory uses electromagnetic induction to heat only the bolt and its immediate surroundings. Because the heat is targeted, nearby components stay cool and undamaged. Therefore, this method is far safer and faster than open-flame alternatives — especially when you are working near fuel lines, brake components, wiring looms, and plastic trim.

Key Benefits

• Flameless operation: There is no open flame, so you eliminate fire risk near fuel lines, plastics, and wiring
• Targeted heat: Induction energy heats only the bolt and surrounding metal, while adjacent components stay cool
• Fast results: Seized bolts typically loosen within seconds, which significantly reduces removal time
• Preserves threads: Controlled heating expands the bolt evenly, and as a result you reduce the risk of snapping or thread damage
• Handles corroded and thread-locked fasteners: The heat breaks down rust bonds and adhesive thread-lock compounds effectively
• Easy to use: Simply connect the bolt heater to your I-Ductor and then position it over the fastener

Compatibility

This bolt heater works exclusively with the Wielander & Schill I-Ductor heat inductor. It connects directly to the I-Ductor unit and draws power from its induction generator. If you do not already own an I-Ductor, then please contact us to discuss the full system.

Technical Details

Typical Applications

The bolt heater is especially useful in bodyshop and mechanical workshop environments where seized fasteners cause daily delays. For instance, common applications include:

• Suspension bolts and subframe fixings that have corroded due to road salt
• Exhaust manifold studs and flange bolts
• Brake calliper and disc retaining bolts
• Thread-locked chassis and structural fasteners
• Rusted underbody and wheel arch fixings

Furthermore, because the bolt heater produces no sparks or open flame, it is also ideal for vehicles with LPG or CNG conversions, hybrid battery enclosures, and any area where you need to minimise fire risk.
