the minor diameter should fall between 4.917mm - 5.153mm
40 threads per inch. The thimble has 25 divisions. Every 1 turn moves the spindle .025 and .025 x 40 = 1.000 .
threads per inch
In the context of a hex bolt specification such as "5-16NC," the "NC" stands for National Coarse. This indicates the thread pitch of the bolt, specifically that it follows the National Coarse thread standard. National Coarse threads have fewer threads per inch compared to National Fine threads, making them better suited for applications where rapid assembly or disassembly is required.
The standard measurements for faucet threads are typically 1/2 inch in diameter with 14 threads per inch for the male end and 3/4 inch in diameter with 14 threads per inch for the female end.
Taps and dies are used to thread . A tap threads a hole and a die threads a rod.
To determine the correct way to read thread sizes, you need to look at the diameter and pitch of the threads. The diameter is the measurement of the threads' thickness, while the pitch is the distance between each thread. The size is typically written as diameter x pitch. For example, a thread size of 1/4-20 means the diameter is 1/4 inch and there are 20 threads per inch.

To determine if your pedals are 1/2 or 9/16 in size, you can use a pedal wrench to measure the diameter of the pedal threads. Pedals with 1/2 inch threads will have a smaller diameter compared to pedals with 9/16 inch threads. You can also refer to the manufacturer's specifications or markings on the pedals for confirmation.
M24 represents the outside diameter(O.D.) of the threads and the 2 represents the pitch of the threads(the distance between each thread).
Thread series cover designations of diameter/pitchcombinations that are measured by the number of threads per inch (TPI) applied to a single diameter
The major diameter is the diameter of the crest of the thread. Use a Vernier gage and mesure the diameter of the crest points of contact ( maximum external thread diameter). Unified National thread series defines the expected major diamter and tolerance. For internal threads ( nuts) the major diameter is the diameter of the roots of the thread.
Pipe threads are stated in terms of so many threads per inch. For instance, a bolt designated as 1/4-20 is a 1/4 inch diameter bolt with 20 threads per inch. Divide one inch by 20 to find the pitch distance.

The nominal diameter of a bolt is the approximate size of the bolt shaft. It is determined by measuring the diameter of the threaded portion of the bolt shaft, excluding the threads. This measurement is standardized based on the bolt's size and type.
1 and 1/2 inches.Depending on the piping diameter one normally would figure for a 1/2" pipe 1/2 for threads
