LK-M Thread Plug Gauges Go/No-Go for SELF-LOCK Threads - Emuge Franken

The gauging of the EMUGE SELF-LOCK thread
We recommend using our two-piece gauge system which corresponds to the usual combination of go and no-go gauge and is perfectly sufficient for the gauging of the thread, provided that the LK threads were produced with our true-to-profile EMUGE taps.
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 gauging EMUGE SELF-LOCK threads exclusively with EMUGE SELF-LOCK gauges.
