AKRON — Releasing a frozen nut from a bolt or stud may require carefully slicing through that nut with the proper cutting device. Here's how to do it.
Removing rusted, frozen nuts is an automotive fact of life; it may be an unpleasant, unprofitable chore.
With some luck, simply soaking a frozen nut with a professional-grade penetrating lubricant beforehand will enable a technician to loosen it easily.
On the other hand, some badly frozen nuts don't readily cooperate with removal efforts. Worse yet, some of these are in somewhat inaccessible locations.
In my last column, I discussed the induction heating technique. This is a flameless heating procedure that loosens a wide range of frozen nuts very efficiently.
However, some readers have asked me about alternative methods because they don't have an induction heating tool.
Carefully cutting a slot through a frozen nut seems to be an overlooked method.
Mind you, it's not a flawless approach. But it still may be an inexpensive but effective approach in many instances.
The accompanying photographs show the technique being used on some Honda “castle” nuts on an exhaust manifold.
