Mitutoyo 516-931-26 Steel Gage Block Set 9 Piece

Product Description

The MITUTOYO 516-931-26 is a 9-piece rectangular steel gage block set designed for precision dimensional measurement and calibration work. Manufactured to Grade AS-1 per ASME B89.1.9-2002, these blocks cover a range from 1/16 inch to 2 inches. Tolerance values are 8 microinches for blocks in the 0.0625 to 0.4 inch range, 12 microinches for the 0.5 to 1 inch range, and 16 microinches for the 2 inch block. Each block is individually serialized and the set ships with a NIST traceability certification. This set is used by machinists, metrologists, and quality control technicians who require verified dimensional references in shop or lab environments.

This gage block set is suited for precision measurement applications in manufacturing, tool and die, inspection, and calibration settings. The ASME B89.1.9-2002 standard compliance makes this set appropriate for use in quality control programs requiring documented measurement traceability. The range from 1/16 inch to 2 inches covers common gauge and setup requirements found in both production and metrology lab environments.

Compatibility

Designed as a Grade AS-1 rectangular steel gage block set compatible with standard wringing techniques and dimensional reference applications conforming to ASME B89.1.9-2002.

Installation Notes

Gage blocks should be handled and stored by trained metrology or quality control personnel. Clean block surfaces thoroughly before wringing to avoid contamination that can affect accuracy. Store blocks in the provided case in a temperature-stable environment to minimize thermal expansion effects. Do not drop or impact blocks, as surface damage will compromise measurement integrity.
