Precision ground M8 x 1.25 Internal thread plug gauge 6H tolerance class GO and NOGO at opposite ends of black hexagon shaped holder body

Great for production situations or to check on performance of threading taps in combination with various lubricants, speeds, feed pressure on differing materials. You would be surprised at the difference when one element of the process is changed and a gauge can make it much easier to understand what has occurred. No other way to check it.

Other sizes of Plug and Ring gauges available with specials or non standard sizes available on a short lead time. Metric, BSW, BSF, UNC, UNF, BSPP, BSPF(T)
