Features:

  • Drilling - clear the damaged threads with a standard drill. (to repair a spark plug thread no pre-drilling is necessary if using the special spark plug tap), please pay attention that for fluteless taps bigger holes are required.
  • Checking - check that the thread and pitch of the tap and the bolt match.
  • Tapping - use the special taps for cutting the holding thread into the cleared hole (recommended to use a suitable cutting oil).
  • Install the insert - place insert on installation tool and position the adjustable ring so that the insert tang is centered in the tang slot. Wind the insert in with a light downward pressure until a half turn below the surface. Don't work against the thread direction as the tang could break.
  • Tang removal - After finishing lift the installation tool and use the tang break tool to remove the tang. For bigger sizes and spark plug taps use long nose pliers to remove the tang. Due to the narrow and exact tolerances the new thread normally is stronger than the original ones.

Item came as described and worked well to repair a stripped out 6mm x1 hole in an aluminum block. Materials appeared to be of good quality.

Fixed my stripped thread on my Motorcycle.

Worked great, drill size is the right size for the tap.

Nice fix for stripped aluminum

Worked great to repair stripped caliper mounting post on a Fox mountain bike suspension fork. I did not have any trouble using this, but the coil took a little bit of fiditing to get threaded into the tapped hole. Overall a great deal, saved me a few hundred bucks!

Perfect!

Just what I needed! fixed my motorcycle rotor.
