    How to read this feeler gauge?

    They have two numbers on each gauge and they are interlaced with the next highest gauge too. Eg. (not sure about the numbers off the top of my head)
    gauge 1: .004 / .006
    gauge 2: .005 / .007
    gauge 3: .006 / .008
    gauge 4: .007 / .009

    So lets say 4 doesn't fit, but 3 does fit. So is the value .006, .007, or .008?

    How old is that gauge? Is it a cheap one? I've never seen one that has that much variation for a single gauge. I'd get rid of it and get one that has one measurement for each gauge or one that has a corresponding metric measurement as well as the SAE measurement on it. .....sean

    i corrected my values to the actual ones on the gauges. They do have metric as well, but still two values for each gauge in mm as well as in.

    Is the end of the gauge thinner than the body? It sounds like a set of GO/NO-GO gauges, with a .002 tolerance.

    example: If the tip of #3 would fit into a gap, but the shank would not fit, the gap is between .006 and .008, checked with one tool.

    Wrong. Only expensive feeler gauges are go/no go. Most are in .001" (or metric equivelent) increments.
    I have a set of Starret's in .0005" steps. They weren't cheap.

    the go/no go rung a bell. I called my friend (who bought them and left them over here) and he said that's what he thought those were because autozone said that was the best type to get. I alwasy wondered why only part of the gauge would fit under the lobe.
