## Overview

The Powerbuilt 14mm Back Tap Spark Plug Thread Repair Tool features a patented collapsible design that expands inside spark plug holes to restore damaged threads efficiently. Made in the USA and ANSI certified, this lightweight 160g tool removes debris while repairing, enabling professional-grade thread restoration without removing cylinder heads.

## Description

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 Back tap repairs the damaged thread as it is drawn up through the spark plug hole, bringing debris and metal filings with it.

Review: Was skeptical but it worked - Restored the thread of a spark plug hole in my Renault cylinder head which had been lightly threaded a few turns. As other reviewers have said, take your time to figure out how the tool works before going in. I passed it through three times as instructed and needed pliers to expand it because of tight access.
Review: Take your time and it works - I printed out the 5 star review by HarleyRider, and carefully followed its advice. Result: I sorted out a crossed spark plug thread on my 1972 T series Bentley, without having to remove the affected cylinder head.
