They are the best thing for things that need to removed many times over the life of the product eg spark plugs, oil pan drain bolts and the like. They are specified for spark plugs and some aluminum applications because the insert is also aluminum and the heat transfer is the same for the insert as the base metal, aluminum expands much more than steel and consequently the coil could loosen, the plug heat range is also not effected.
This aluminum expansion is the reason valves in an aluminum head tend to get more clearance when at operating temps not tighter like an iron head.
They are not a replacement for a heli coil in every application, just an additional tool to do a proper repair.
It was just a suggestion. But you seem to know best so carry on. Shocks should be changed just as often as spark plugs so that is a poor example. If done properly it should last the life of that control arm.
