Tempco Bolt Cartridge Heater HDB00027

The Tempco Bolt Cartridge Heater HDB00027 from Thermal Devices, an authorized Tempco distributor. Bolt Heaters are used as an aid to tighten large bolts in heavy machinery and equipment. Heaters are sized for easy insertion into a hollow bolt. The rapid heating of the bolt expands it, allowing further tightening of the nut. The heater is then de-energized and removed. As the bolt cools, its contraction back to original size provides a tight fit.
