After measuring the threads on a fitting, you must match the number to a thread.

The reading shown is the size of the nut as a decimal. Uses threads per inch, while other parts of the world use a metric thread pitch. While a ruler could be used to calculate the pitch size, a pitch gauge is highly recommended as pitch sizes can be very similar.

If the nut is metric, count the number of lines on the tape measure to find the measurement. A thread’s pitch size is the number of threads per inch or the distance between threads on metric thread types. Similarly, how do i know what size nut i need?

Inch thread sizes are specified by diameter and threads per inch. If the nut is metric, count the number of lines on the tape measure to find the measurement. The important thing here is that you need to print them out at actual size.

But it is easier to specify the components by a single size designation since the bolt and nut are mating components.) pitch (thread pitch) pitch is the distance from the crest of one thread to the next or the distance from one thread groove to the next, measured from crest to crest. If you count 11 lines, the size of the nut is 11/16. Use a thread pitch gauge to determine the number of threads per inch or the distance between threads in metric connections.

This is the size of your nut and required socket. The bolt depot has some excellent charts that you can print off for both imperial and metric fasteners, as well as nuts and washers. This is the measurement that you need to take across the outside diameter of the wheel stud thread.
