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.

We carry an extensive inventory of test & measurement equipment, with over 3000 products available for same-day shipping.
