Bolt Heaters

 

Designed primarily to pre-heat large, drilled holding bolts or studs. The Bolt Heater is used in the assembly or servicing of hydraulic presses, die blocks, steam or pressure vessels, turbines or other equipment where a high concentration of heat is needed to expand, then wrench tighten tie rods. The parts cool and contract, resulting in the nut being drawn even tighter
