Tolerance specification

Tolerance specification refers to the allowable variation in a manufactured part’s dimensions or properties to ensure proper function and compatibility. It defines the acceptable range within which a component’s measurements can deviate from the target size or shape without affecting performance. For example, a screw might be specified with a certain diameter and tolerance, meaning it can be slightly larger or smaller within those limits. This helps manufacturers produce parts efficiently while ensuring they fit and work correctly in assemblies. In essence, tolerances balance precision with practicality, maintaining quality without unnecessary strictness.
