Bright Mild Steel

[Harry WilkesParticipant @harrywilkes58467]

Purchased some 0.125" bright mild steel round I find it to be 0.117" I understand that I may have been supplied 3mm, but lets say it is imperial what sort of tolerance should I expect ?

It is 3mm. I'm not certain but I believe 1/8" has been unavailable for many years.

Couple of thou at the most. I can still by 1/8" but get through more 3mm these days.

You've bin dun, the whole point of "bright" is that it is close to size otherwise you would be happy with black bar.

Ask if they have any 3.2mm.

I can't find any tolerances for Bright Imperial Round Drawn under 1/2" diameter, which is -3 thou to 0.0

Bright Metric Round Drawn under 6mm diameter should be -0.07mm to 0.0

What you have is certainly in spec for metric 3mm, and given Imperial doesn't seem to specify tolerances below 1/2", it could be street 1/8" too! Bet its 3mm though.

That's always been my rule-of-thumb, more-or-less irrespective of nominal size up to maybe an inch or so. Don't have much experience of larger.
