What do we call a tolerance that applies to a specific dimension?

A tolerance that applies specifically to a given dimension is referred to as an explicit tolerance. This type of tolerance is clearly defined in the manufacturing drawings or specifications, outlining the acceptable limits for that particular dimension. Explicit tolerances provide precise guidance for fabrication or inspection, ensuring that the finished component meets the design requirements.

In contrast, general tolerances might apply broadly to all dimensions on a drawing unless specified otherwise, and implied tolerances are often understood through the context of the drawing but are not explicitly stated. Absolute tolerance refers to a fixed measurement that establishes a specific boundary but does not necessarily indicate application to a singular dimension or context. Thus, when a tolerance is designated for a specific dimension, it is most accurately described as explicit.
