Powerbuilt 18mm Back Tap Thread Repair Tool
The Back-Tap's patented collapsible design allows it to engage be placed through the spark plug hole and into the chamber. A mandrel is then drawn back, expanding the tool's threaded area and threading into the clean threads at the bottom of the spark plug hole. The Backtap repairs the damaged thread as it is drawn up through the spark plug hole, bringing debris and metal filings with it.

This tool saved me the hassle of pulling off the head and costing me hundreds of dollars. Now that I have it, I can be rest assured that I have if I need it for the next problem.

I don't expect to use this very often, but it will be very handy when I need it.

I have several other sizes of the Powerbuilt tap. All the others had the Powerbuilt name and the size laser engraved on them. This one has no markings at all. The others had a Powerbuilt red vinyl bag, this one did not. The others also came in a cardboard/clear plastic blister container with instructions and company info. This unmarked tool was in a small plastic bag. I doubt this is genuine.

Did not come with the case as shown nor with any instructions. Very disappointing purchase.
