Stripped or Damaged Spark Plug Threads

 
 

Damaged spark plug threads can sometimes be reclaimed or improves by using a "thread chaser" but stripped threads can only be reclaimed by using a wire insert (Helicoil)
or a solid one such as a "time-sert".

 

Time-sert Key serts wire insert

We can fit helicoils etc at our premises or yours

 
     

 

     

Broken drills, taps and studs with broken extractors can
ONLY
be removed safely by spark eroding.

Our mechanics are trained in the use of portable spark eroding equipment
to remove broken taps, drills extractors etc.,
 and in the fitting of inserts to reclaim stripped internal threads.
