Bolt Heaters

Bolt Heater is designed primarily to pre-heat large, drill holding bolts or studs. The Bolt Heater is used in the assembly or servicing of hydraulic presses, 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. A terminal box of octagon or circular shaped is fixed on the top where the terminals are provided and an insulated wooden handle is provided for shoving the heater inside/ outside the tunnel.
We manufacture Bolt Heaters in the form of Split Sheathed Heater complete with Terminal Box & holding and an insulated wooden handle.
