SUGGESTED GAGE TOLERANCE =

0.0002 = CLASS ZZ
 

For best value, determining the proper tolerance is significant. Using the Class Z (.0001), when a Class ZZ tolerance (.0002) is acceptable, reduces the potential 'wear factor' by 50%. Using a Class X tolerance (.000040), when a Class Z tolerance (.0001) is acceptable, reduces the potential 'wear factor' by 60%.
