Closest metric drill size
15 mm
19/32β³ = 15.08125 mm Β· difference 0.0813 mm
Metric drills step in 0.5 mm, so a fractional inch size rarely lands exactly on one. A 0.0813 mm gap is usually invisible in a clearance hole but changes the fit on a press fit or a tapped hole.

Matching it to metric
The nearest metric drill size is 15 mm, a difference of 0.0813 mm. Whether that matters depends on the job: a clearance hole tolerates it, a press fit or a tapped hole does not. For hex fasteners the same logic applies to socket sizes β a socket even a few tenths oversize will round the corners of the head.
