Nominal overall square dimensions will be the overall for the equivalent round size plus .0001"-.0003".
Minimum and maximum overall dimensions will be the same as those for the equivalent round size.

Example: 22 Square Heavy Build

Nominal

O.D. = .0277"-.0280"

Minimum

O.D. = .0271"

Maximum

O.D. = .0281"


Conformance to dimensional tolerance is based on the average of at least three measurements per axis using a minimum 12" sample length. Individual measurements outside the tolerance limits will not be cause for rejection.
