I was able to repair a damaged lug bolt on a car that otherwise would have had me tearing apart my suspension or taking a grinder to it in order to replace. Really cool design that saved the day.
Pros
By repairing threads on existing wheel studs and bolts, the Steelman Thread Chaser can help save time and money that would otherwise be spent on complete part replacements
Cons
The indexing pins may cause damage if not aligned correctly with the threads being repaired
