- Confusing it with a 'ring gauge' used in jewellery (for measuring ring size), which is a different, non-precision tool.
FAQ
Frequently Asked Questions
No, they are complementary. A ring gauge checks external diameters (e.g., of a shaft), while a plug gauge checks internal diameters (e.g., of a hole).
In highly technical jargon, it can be used verbally (e.g., 'to ring-gauge a part'), but this is non-standard for general English. Prefer phrases like 'to check with a ring gauge'.
A 'go/no-go' ring gauge has two ends: one ('go') should fit over the part if it is at the minimum acceptable size or smaller; the other ('no-go') should NOT fit if the part is at the maximum acceptable size or larger. It provides a quick pass/fail test.
In American English, particularly in engineering and manufacturing contexts, 'gage' is a common variant spelling. However, 'gauge' is the standard spelling in both UK and US English for most general uses.
