PMC Mercury Plain Cylindrical Gages are custom made-to-order using American Gage Design standards
These gages are used in quality processes of laboratories and shops to gage parts being manufactured as well as calibrating equipment. Selection of gage tolerance should be in relation to the amount of tolerance on the product being gaged. The normal practice is that the gage tolerance should not exceed 10% of the product tolerance. Gages are furnished in four classes of tolerance, XX, X, Y and Z.
