- Jun 24, 2013Anti backlash nuts can be used to eliminate backlash even on low precision acme thread if that is all that is required.
A precision class acme thread will have a tighter tolerance between the thread pitches.
For example 10tpi thread
2G class has a tolerance of .0095
3G class has a tolerance of .0044
2G class has a tolerance of .0032
