FAST and PERMANENT THREAD REPAIR
Do you have a thread-repair problem?  We can help.
You’re probably familiar with ordinary thread-repair inserts –  Heli-Coil ® (spring type), KeenSert® (pin type), E-Z Lok® (glue type).  And others.  These have all been around for a long time, and they’re good products.  So why do we call them “ordinary”?  It’s because usually they work, but sometimes they don’t.  When they don’t, you end up with an even bigger problem.
C-Serts work.  Guaranteed.
They succeed in the heaviest, most demanding, highest torque industrial applications.
They won’t wear out, back out, or pull out.  And they’re by far the fastest and easiest to install of all thread-repair inserts.
