1pc,0.5-100mm Length, Ceramic Rectangular Gauge Block, Grade 0, Customized Gauge, Tools For Micrometer And Caliper Inspection for Woodworking(5mm 1pc)

1. Grade 0 gage blocks are commonly used within a controlled environment as reference standard for setting high precision measuring equipment, to calibrate low-grade gage blocks, inspect the accuracy of gages, and mechanical parts and tools 2. Ceramic blocks are harder than steel, and abrasion, and burrs, withstand high temperatures without melting (high thermal expansion resistance), and provide dimensional stability 3. Rectangular-shaped blocks provide accurate wringing 4. The nominal length of each block is measured in milimeters(mm) 5. The material has high hardness and good wear resistance. Its service life is 4-5 times that of steel gauge blocks
