Threads are called out by O.D. The metric thread cable gland is one of the most popular types of cable glands, the dimensions ranging from M6 to M100, which means the hole size in mm must be exactly same like this size chart..

ISO 262 “ISO general purpose metric screw threads — Selected sizes for screws, The data below represents the dimensions of metric coarse machine screw threads as defined by ISO standards. * Nominal diameters for BSP and NPT are not thread diameters but relate to the inside diameter of the pipe. The next step in identifying your thread type is to determine the pitch size. ISO Metric Machine Screw Thread Dimensions. The tap size chart provides a list of standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes. While AN fittings depend on the outside diameter of a tube for sizing, NPT fittings depend on the interior diameter (I.D.) Use the dimensions of your bolt to determine the appropriate size nut.

The metric world eventually agreed but not formalised in 1898 on the Systeme Internationale (SI) metric thread series, with a 60-degree thread angle. Thread identification means learning the thread size and pitch. The following chart shows the each size's thread-per-inch count, the I.D. It is generally the basic major diameter of the thread”. Thread Conversion Table Due to the differences in thread angles and pitches, the thread sizes shown below are not directly interchangeable with each other.
