Pin and hole tolerance test log

One printed pair per row. Record the recipe, the nominal model dimensions and what you actually measured. Leave a field blank when you did not measure it; blank is not zero. Diametral clearance is hole diameter minus pin diameter, so the gap per side is half of it.

Recipe and process
