Specification Brand : DAUZ BulletPoint1 : HIGH ACCURACY: Gauge blocks have a high accuracy, low roughness, and good grinding force; Other accuracies used for calibrating instruments. BulletPoint2 : CALIBRATION MEASUREMENT: Thickness gauge block group is ground and polished to have a very low micro finish; They have an accuracy of ± 0.00005in. BulletPoint3 : STEEL MATERIAL: Made of premium steel after heat treatment, the gauge block has the characteristics of high accuracy, low roughness, good bonding force, and stable size. BulletPoint4 : MAIN FUNCTION: Gauge block is the highest accuracy benchmark for converting broadcast wavelengths into physical length sizes. And by comparing and measuring, transfer the dimensional annotation techniques to accuracy gauges, measuring tools, and workpieces. BulletPoint5 : 32PCS: There are 32 pieces gauge blocks in the box and are well identified for convenient using and storing, choose and use at will!
