M16 x 2.0mm Tap Set

Lyndon Tap Sets consist of a taper, a second and a plug. The taper has the thinnest end, and so will enter the hole more easily. The second has a larger end, so it will make the threaded hole larger towards the bottom of the hole. The plug is the same width all the way down and is necessary when tapping a blind hole which requires the same size thread throughout the whole length.
