NEED MM THREAD SIZE PLEZ

[riversidedan]

dealing with a nut that has a 6.0x1 mm size, hoping someone can translate that , thanx

6 MM is a standard metric size, do you need the imperial equivalent measurement? 1MM = 0.03937 inches X 6 = 0.2362 inches

I have a model engine that needs a shaft nut and need to know what size tap to get

Obviously the tap size you need is a M6 X 1.

A regular M6 tap has a 1mm thread pitch.

A regular M6 tap has a 1mm thread pitch.

so an M6 tap will already have a 1mm thread pitch??

There is a rare M6 x 0.75 found in the wild but M6 x 1.0 is the common one.

An M6 x 1 Translated: M for metric, 6 for the nominal diameter in mm, 1 for the thread pitch (1mm crest to crest) Tap drill size is = to the nominal diameter minus the thread pitch (6-1=5mm, find the drill closest if you don't have metric drills. That is a very common size, similar to 1/4" Imperial but won't interchange. Many configurations of taps are available. Easiest to use by hand is a taper tap, next is a plug tap. A bottoming tap should only be used after one of the others as it is almost impossible to start straight by hand in a drilled hole.
It sounds like you have little experience with tap & die use. Watch some videos before you try it. Tapping fluid helps but even almost any oil will work better than nothing. No fluids are used on cast iron. Go easy and back the tap out often to clear the chips and keep it from breaking. It is all too easy to break small taps. Probably worth practicing on some similar metal before the good part. Be very careful to start straight. Taps are hard and brittle!

You might need two taps: a standard "plug" or taper tap and a second "bottoming" tap if it's a blind hole and you need threads nearly to the bottom

Edit: I see Larry already mentioned that above

I just checked my new 110 piece metric tap set and there are three pitches in 6mm.

1x6MM
.75x6MM
.8x6MM
