H 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. Dave Dave
