Description:  Gauge Block are precsion retangular block used to check the tolorence 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.

 

      -----Rok Gauges meet or exceed all known specifications.

      -----Long life span,not easy to wear out.

      -----Highly accurate, very low deviation from flatness, surface finish

      -----High resistance to wear & dimensionally stable.

      -----Each gauge block is marked for size
