Snap gages are used in production environments where specific diametrical or thickness measurements must be repeated frequently with accuracy and precision. Snap gages are mechanical gages that use comparison or the physical movement and displacement of a gaging element such as slide, spindle, or stem to determine the dimensions of a feature or part. Snap gages are available in both English and metric measurement configurations and in fixed and variable forms. The variable forms often have movable, top sensitive contacts attached to a comparator or indicator. Popular brands of Snap Gages include both Mahr Federal and Mitutoyo. MSI Viking is your one-stop source for these brands and more.
