Part Number: M1-3
10mm x 1.0 Fine thread, male steel nut with non-threaded lead, 17mm long overall 
SAE flare (45 degree inverted/double) or DIN flare (bubble/ISO)
This is the standard European (German, DIN) style brake line nut used with 3/16"/4.75mm tube.
Found with both SAE and DIN flares.
It is now appearing everywhere, including late model American and Japanese cars.
If you have a Bosch ABS pump, you may have these nuts.
The 10mm x 1.0 nut is a bit larger and has a finer thread than the 3/8” x 24 unf American nut.
Caution, the 10mm nut will start in a 3/8” x 24 unf hole but will strip the threads as you tighten it.
Used with UM14-3 union.
