Thisthread identification number gives, when multipliedby 5, the nominal thread diameter in millimetres.The only exception to this is locking nuts of theseries HM 30 and HM 31. For these types the basedesignation consists of a four-digit number wherethe first two numbers identify the series and thesecond two numbers indicate the size of the thread.For locking nuts with thread diameters larger than500 mm the nominal thread diameter is writtenbehind the base designation, separated by anoblique slanting line.Examples:KM Standard lock nut with metric ISO-threadKM30Lock nut with metric thread M 150x2.Outer diameter 195 mm.KML Lock nut with metric ISO thread; narrowercross section compared to standard KMlock nuts.KML30Lock nut with thread M 150x2.
