The Tempco Bolt Cartridge Heater will help assist with tightening large bolts in heavy machinery and equipment. The heater is the perfect size for easy insertion into a hollow nut. Then the heater is de-energized and removed once the bolt cools down. This process allows the fitting to contract back to the original size to provide a tight fit. These heaters can be configured to your specific needs with insertion lengths, diameter, heated lengths, voltage and wattage requirements. Many industries will utilize these heaters such as power plants, shipyards, large machine and die manufacturers, construction and boiler manufacturers.
