Mitutoyo 516-926-26 Gage Block Set 10 Piece Steel

Product Description

The MITUTOYO 516-926-26 is a 10-piece steel gage block set covering a measurement range of 0.005 to 0.05 inches. Each block is manufactured to Accuracy Grade 0, the highest precision classification under ASME B89.1.9-2002, with a flatness and parallelism tolerance of 6 micro inches. The set is individually serialized and ships with an inspection certificate and a wooden storage case. Dimensional metrologists, quality control technicians, and calibration lab personnel use these blocks to verify measuring instruments, set comparators, and establish precise reference standards in production and inspection environments.

This gage block set is suited for precision measurement applications in manufacturing, metrology labs, and tool rooms where tight dimensional verification is required. The 10 step increments progress in 0.005-inch intervals from 0.005 to 0.05 inches, providing a compact but practical range for calibrating micrometers, height gauges, and other contact measuring instruments. The included wooden case keeps blocks organized and protected between uses, reducing the risk of surface damage that would compromise wringing performance or calibration integrity.

Key Features

• Accuracy Grade 0 per ASME B89.1.9-2002 — the highest precision grade in the standard
• Tolerance of 6 micro inches for flatness and parallelism
• Range of 0.005 to 0.05 inches in 0.005-inch step increments (10 blocks total)
• Steel construction for durability and long-term dimensional stability
• Individually serialized blocks with traceable inspection certificate included
• Wooden storage case included for protection and organization

Compatibility

Designed as an OEM-specification gage block set suitable for use with standard wring-compatible steel gage block accessories and holders conforming to ASME B89.1.9-2002.

Installation Notes

Gage blocks should be handled by calibration technicians or metrology personnel familiar with proper wringing technique and surface care procedures. Before use, clean block surfaces with a lint-free cloth and appropriate solvent to remove oils and debris that could affect accuracy. Store blocks in their wooden case when not in use and avoid exposing them to temperature extremes, as thermal expansion can affect measurement results. Do not drop or stack blocks carelessly, as surface damage will void calibration validity.
