Wire type or reversible plug gages were originated by PMC Mercury in 1923. The wire type design is extremely efficient and economical because the entire surface of the gage may be used and can be reversed or cut-off to increase gage life. PMC Mercury plug gages are a highly accurate, economical and convenient tool for hole inspection where a determination is made of compliance within design limits. Close accuracies can be obtained for laboratories and quality departments requiring precise inspection without the lengthy and expensive set-up time of measuring instruments. The fixed dimension of a plug gage eliminates out-of-calibration and cumulative errors. We suggest using plugs gages as Go/Not Go combinations to ensure the hole meets the low and upper limits of the specified design dimensions. Standard practices indicate that 10% of your product tolerance is divided between the Go/Not Go gages. Go gages are plus tolerance and not go gages are minus tolerance. Our gages are available in four classes of tolerance as standard and may be quoted as Class ZZ.

Ordering Information: Locate your size and tolerance. Go is Plus; Not go is minus and Master is split (bilateral). Specify if you require a member only; member with one single-end handle or a Go/Not Go assembly in a double end handle. Available in Chrome – please call for a quote. Handles will be marked with size, Go/Not Go and your tool number if provided. Gages are shipped in clear vials. Certificate of Conformance or Long Form N.I.S.T. Traceable Certificates are available.
