Metric - Fine, Medium and Coarse, UNC, UNF,  BSP, BSW, BSF,  it is also possible to reclaim some left hand threads.
We carry an extensive range of threaded inserts, both wire (Helicoil) type and solid inserts eg. Time-Serts.

We sell Wurth Timesert Kits and inserts
and EZ-Lok Inserts

If a thread has been previously repaired, eg, on pulled Helicoils, worn or over drilled long as there is enough material
 around the problem area, it can be repaired using various inserts to get the thread to its original specification,

We use Helicoil, EZ-LOK and Timesert products for our thread repairs as they are all made to very high specifications,

We can carry out the repair on site at the customer's premises,
 or in our workshop on items sent to us.
