How to Read Screw Sizes
  1. Read the first letter of the size. This the largest diameter:the measurement of the screw on the thread.
  2. Read the second number. This is either the number of threadsper unit of the distance between threads; also known as the “threadpitch”.
  3. Read the third number, generally the one following the”x.”

M5 x 0.8 Class 6g

As others have mentioned, the TPI is almost identical,so the threads will engage as long as the screw can fit in thehole. But the M5 fastener is almost 4% larger than the10-32, which is enough to cause interference in mostfits.

How do you identify a screw?

As a general rule, the length of fasteners is measuredfrom the surface of the material, to the end of the fastener. Forfasteners where the head usually sits above the surface such as hexbolts and pan head screws, the measurement is from directlyunder the head to the end of the fastener.
