Discover our M24 Metric Thread Page, your comprehensive reference for swift assessments on M24 metric threads. We've compiled an extensive collection of data for all common metric threads you'll use in your parts, outlining crucial measurements like thread pitch, tap drill, and clearance drill. It's an all-in-one solution for engineers, machinists, and hobbyists seeking dependable, precise information.
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 M24 thread is 3 mm.
The tap drill for an M24 thread is 21 mm.
The clearance drill for an M24 thread is 26 mm.
