The following tolerances should be used for general design guidance only. Part design and/or secondary operations can affect these tolerances.
LINEAR TOLERANCES
- Up to 1.00" ±.005"
- Up to 2.00" ±.010"
- Up to 3.00" ±.015"
- Up to 4.00" ±.020"
- Up to 5.00" ±.025"
- Up to 6.00" ±.030"
DISH
Dish is the total deviation permitted from a plane.
Allowable dishing is in addition to the linear tolerance.
