There is no generally applicable standard (e.g. DIN standard) for the EMUGE SELF-LOCK thread, so other manufacturers may use different limit sizes for their threads. For this reason, we recommend gaging EMUGE SELF-LOCK threads exclusively with EMUGE SELF-LOCK gages. The gaging of the saw-tooth profile works on the same principle, with the only difference that both the GO and the NO-GO plug gage have to be used in the correct direction. If chasers or thread milling cutters are used, we recommend using an additional EMUGE HRPG gage. This gage serves to check the lower ramp point or possible ramp angle errors. ≥ 36 T.P.I.
