Rectangular Steel - Inch System B89.1.9 Accuracy Grade 0* ● Greatest Range - .100” to 12.000” in .001” steps ● Greater Efficiency - allows two men to work from the set at the same time ● Greater Accuracy on build-ups - allows using a minimum number of blocks The World’s Most Complete Gage Block Selection Rectangle, Square & Heavy Duty Styles from .010” thru 20.000” These B-Grade gage block sets are Starrett Global products. Their very affordable price makes them ideal for general shop floor use. Now, our initial inch sets are joined by four Metric B-Grade Sets. Etched, unique serial numbers are included on each block. Custom numbers are not available. Sets are available with a choice of two types of certificates of calibration as described below. Inch System sets have a tolerance of ±50 µ in. MicroAccurate® B-Grade Gage Block Sets Specifications Metric System sets have a tolerance of ±1.25 µm Call for info on square and heavy duty sets.
