Mitutoyo 516-423-26 Gage Block Set 36 Pc AS-1 Steel

Product Description

The MITUTOYO 516-423-26 is a 36-piece steel gage block set covering a measurement range of 0.05 to 4 inches at AS-1 accuracy grade. These blocks are used to establish precise reference dimensions for calibration, inspection, and layout work in tool rooms, metrology labs, and production environments. The set meets ASME B89.1.9-2002 standards and includes an inspection certificate, confirming that each block has been verified to grade. Tolerances vary by size: 8 micro-inches for blocks in the 0.05 to 0.4 inch range, 12 micro-inches from 0.45 to 1 inch, 16 micro-inches at 2 inches, and 24 micro-inches at 4 inches. Every block is individually serialized for traceability.

This set is suited for precision measurement applications in manufacturing, quality control, and calibration facilities. Step increments are organized across five groups: nine blocks at 0.0001 inch, nine at 0.001 inch, five at 0.1 inch, ten at 0.01 inch, and three at 1.000 inch. This range of increments allows technicians to build up a wide variety of stacked dimensions for gauging, instrument verification, and machine setup. The set ships in a fitted wooden case that organizes all 36 blocks and protects the lapped surfaces from damage during storage and transport.

Compatibility

Designed as a general-purpose gage block set compatible with standard wringing and stacking techniques used in precision measurement and calibration workflows conforming to ASME B89.1.9-2002.

Installation Notes

Gage blocks are handled and used by metrology technicians and quality control personnel. Before use, clean all block surfaces with an appropriate solvent to remove oil or debris that could affect accuracy. Wring blocks together using proper technique to avoid scratching the lapped surfaces. Store blocks in the provided wooden case when not in use to protect the surfaces and maintain calibration integrity.
