M22 Metric Thread

Below are the key dimensions for M22 metric threads: pitch, tap drill and clearance drill according to ISO 724:2023.
Welcome to our M22 Metric Thread Page, your dedicated hub for quick measurements on M22 metric threads. We've accumulated an exhaustive database for all typical metric threads you'll require for your parts, covering key dimensions like thread pitch, tap drill, and clearance drill. This page is a one-stop-shop for engineers, machinists, and hobbyists looking for reliable and precise details.
All dimensions stated in are mm (millimetre)
The Major Diameter is the largest diameter on the thread and is measured from the thread crest to crest (peak of the thread).
This is the distance (mm) from one thread to the next, this can be measured from tip to tip or groove to groove. Pitch can also be defined as TPI, which stands for threads per inch.
Minor Diameter is the smallest diameter on the thread and is measured from the thread root to root (Bottom of the thread).
The angle between the thread faces. 60 degrees in the example above.
The thread will assemble when rotated clockwise. "righty tighty lefty loosely"
The thread will assemble when rotated counter-clockwise.
The pitch for an M22 thread is 2.5 mm.
The tap drill for an M22 thread is 19.5 mm.
The clearance drill for an M22 thread is 24 mm.
