ADVANCED
IBH Inductors are truly amazing. Rapid-Torc can customize the inductor for
any size stud, and are designed to be flexible in case small adjustments are
needed. Truly amazing components; truly amazing system. Here’s how we
determine the best design.
Thread Length
Rapid-Torc® IBH does not generate heat, as the case with electric, gas and radiant heating
technologies. It uses induction heating, causing the bolt to heat itself. Induction heating
occurs when a material capable of conducting electrical current, not necessarily ferrous or
magnetic, is placed in a varying magnetic field. The material becomes heated as a result of
hysteresis and eddy current losses. Hysteresis occurs with magnetic materials and is proTHE MOST
AND
duced by retardation
of the magnetization effect caused by
the friction of the molecules,
when the material is magnetized in one direction, then reversed at a very high frequency.

Advanced Bolt Heating
Rapid-Torc engineers
saw an opportunity to
greatly reduce wasted
downtime. WIth costs for
downtime quickly escalating, there had to be
a way to work fast, safe
and efficiently. Rapid-Torc
IBH is the answer.
