Description

Brown& Sharpe 598-10-18 gage block micrometer checking set includes a set of 10 gage blocks and two optical flats that are used to verify the measuring accuracy of micrometers with a 0 to 1" measuring range. Two optical flats have a 0.500" and 0.5125" diameter and are used to verify the flatness of anvil faces at half revolutions of the micrometer spindle. Grade 2 high-alloy steel gage blocks have a hardness of 800 HV (Vickers Pyramid Number) and are artificially aged to ensure stability. The gage blocks meet federal specification GGG-C-15c and MIL-STD-45662A, are individually inscribed with a serial number for identification, and include a Certificate of Calibration. Grade 2 gage blocks are commonly used as Working Standards in inspection rooms to set and calibrate measuring instruments and other equipment as well as to inspect tools, fixtures, and machines. Gage block sizes include 0.105", 0.210", 0.315", 0.420", 0.500", 0.605", 0.710", 0.815", 0.920", and 1.00". The gage block and optical flat set includes a fitted wooden box.
