Mitutoyo 611506-531 Individual Metric Gage Block Rectangular Steel ASME Grade - 0.5mm 0

The Mitutoyo 611506-531 is a 0.5mm individual metric gage block from Mitutoyo's Series 516 lineup. Part of the foundational precision measurement tools used in manufacturing and quality control, this rectangular steel gage block is rated to ASME Grade 0, making it well-suited for use in inspection areas to verify the accuracy of plug and snap gages, as well as for setting and calibrating electronic measuring devices.

Key Features:

• Nominal Size: 0.5 mm
• Shape: Rectangular — optimized face geometry enables accurate wringing for reliable stacked measurements
• Material: High-carbon, high-chrome steel — provides exceptional hardness and long-term wear resistance; methodically repeated heat treatment reduces dimensional change over time
• Grade: ASME B89.1.9-2002 Grade 0 — suitable for inspection room use and verification of working gages
• Tolerance: ±0.10 microinch — meets or exceeds all known ASME specifications for flatness, parallelism, and surface finish
• Face Length: 30 mm
• Supplied with a Certificate of Inspection confirming dimensional accuracy

Mitutoyo's Series 516 individual gage blocks are available as discrete pieces, ideal when a single specific size is needed repeatedly without purchasing a full set. These blocks conform to ASME B89.1.9-2002 standards and are manufactured to meet or exceed all government dimensional accuracy requirements. The rectangular form ensures reliable wringing performance, allowing blocks to be stacked and combined for precise custom measurement stacks.
