Description:  Gauge Block are precision rectangular block used to check the tolerance of measuring tools , such as caliper, micrometer, ect. The large size are check the caliper or micrometer ranging from 300-1000mm by clamping two blocks together. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness, In use, the blocks are stacked to make up a desired length. Precision gage blocks are the primary standards vital to dimensional quality control in the manufacture of parts. Rok International Industry  has always offer customers with high quality products, making your calipers and micrometers more accuracy.
