Precision Cylindrical Plug & Ring Gages
Zero Check has always prided itself as an innovator. This has enabled Zero Check to be the leader in the manufacture of precision gages.

From the very beginning, Zero Check recognized the need for an economical unilateral plug. The manufacture of Class Z go and no-go wire-type gages was the answer to this need. Later Class Y, X and XX quality gages were added for off the shelf service to satisfy customer immediate needs.
