Chase ‘em Back Tools
If you’ve spent much time working on cars,
you know how nice it can be to have a tapand-die set ready to go. Especially, when you
manage to damage the threads on a bolt or a
threaded hole, or when you discover that
the guy who got there before you did. But
even if you have the taps and dies ready to
go, executing the repair often requires some
finesse, which in turn takes time.
In cases involving studs, or even bolts,
we recently discovered a new method of
approaching the repairs that should ease the
difficulty, and the amount of time involved in
coping with the initial threads that have been
damaged. These are the situations where
getting the tool to even begin the repair is
a challenge, requiring detailed filing, and
sometimes leading to further damage.
Chase ‘em Back Tools developed its Hinged
Reverse Thread Chaser as a means of quickly
repairing damaged threads in the field. The
tools look similar to conventional dies, except
that they are split into two halves. The halves
are hinged, which allows them to be opened,
positioned over the lower portion of the
stud, or bolt, where the treads are still intact,
and then closed and fitted into the supplied
wrench so that the
tool can be worked
up towards the end
of the stud, using the
undamaged threads as
a guide.
For the most part,
once the Hinged Reverse Thread Chaser
is positioned over the good threads, the
procedure of straightening out the damaged
threads is the same as using a conventional
die. You must use some sort of cutting
lubricant, and you get the best results by
carefully “working” the tool, going back and
forth against the damaged portion of the
threads to re-establish the proper pattern.
