Gage Blocks

A gage block is a block formed from hard steel, ceramic, or another resilient material. It is precisely made to an exact length for use in standardizing measurements. Gauge block sets provide length ranges which can be stacked. Their lengths can be combined through wringing – joining block ends so that the faces form a light bond. Classified by tolerance grades, a gage block serves as a primary standard for dimensional quality control during parts manufacturing.

Transcat is your premier provider of gage blocks for the best names in the industry, such as Mitutoyo, Starrett, and Ashcroft. We carry an extensive inventory of test & measurement equipment, with over 3000 products available for same-day shipping. We also offer ISO 17025 Accredited Gage Block Calibration Services, which can be performed on either your current assets or new instruments purchased from Transcat.
