THREAD DEPTH MARKER

THREAD DEPTH MARKER
When tapping tapered pipe thread for oil or coolant passage plugs in blocks and cylinder heads, it is important not to tap too shallow nor too deep. A length of soft copper wire, twisted around the tap, works much better than tape or a Sharpie mark to indicate the proper depth. The copper wire stays in-place for hundreds of uses, saving engine builders much time and frustration.
