Dimension tolerance

Refers to allowable range of dimension variation

0.059” ± 0.008” thick ⇒ 0.051” – 0.067”

0.059” ± 0.004” thick ⇒ 0.055” – 0.063”

0.004” closer (tighter) tolerance than 0.008”

Tolerance specifications often indicated for dimensions of all product forms

Different production processes result in different tolerances
