Comparing:
M1.6 Thread
M10 Thread
M1.6 is a miniature ISO metric machine screw thread with a nominal major diameter of 1.6 mm and a standard coarse pitch of 0.35 mm. Requiring a 1.25 mm tap drill, it is the standard fastening thread for precision optical equipment, wristwatches, and micro-electronic assemblies.
M10 is an ISO metric machine screw thread with a nominal major diameter of 10.0 mm and a standard coarse pitch of 1.50 mm. Requiring an 8.50 mm tap drill, it is standard in automotive engine mounts, suspension control arms, motorcycle rear-view mirrors, and commercial HVAC hanging brackets.
