Mekanik 14mm x 1.25 Spark Plug Thread Repair Tool Kit M16 Tap W/Portable Case,Tap Tool,Spark Plug Tool

This set of thread repairer inserts comes in a neat and handy case.Good quality and easy to use. I have used one of these inserts on a wheel nut and torqued up to 100Nm, holding well.

While the quality of this product was good the cutter was not as shown in the picture. The cutter that came with the project was a plug tap which necessitated the drilling out of the original thread before a thread for the inserts could be cut. This meant that proper alignment of the tread was difficult. I therefore returned the item as not as described. An instruction leaflet would have been useful.

In my case it was impossible to start the thread cutting tool into an aluminium head spark plug hole making the tool unusable.

Can’t recommend these enough. Saved me a trip to the garage and £££

Absolute junk and can't return because royal fail are not open when I finish work !!!!
