Mitutoyo 611122-531 Steel Gage Block 0.1002 in Grade 0

Product Description

The MITUTOYO 611122-531 is a rectangular steel gage block measuring 0.1002 inches in overall length, manufactured to Grade 0 accuracy. Gage blocks are precision ground and lapped reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy in machine shops, toolrooms, and quality control labs. This block ships with a Certificate of Inspection, confirming it meets ASME standards for Grade 0 tolerance. Grade 0 represents a high level of dimensional accuracy suitable for calibration work and close-tolerance inspection applications. Machinists, metrology technicians, and quality engineers are the primary users.

This gage block is suited for toolroom and laboratory environments where verified dimensional references are required. It is used as a single-block reference standard or as part of a wrung stack to achieve a target measurement. Typical applications include setting dial indicators, calibrating micrometers and calipers, and establishing reference datums on surface plates. The rectangular form and steel construction are standard for general-purpose metrology work in both production and inspection settings.

Key Features

• Grade 0 accuracy per ASME standards, suitable for calibration and precision inspection
• Nominal size of 0.1002 inches for close-tolerance reference work
• Rectangular steel construction for durability and stable dimensional integrity
• Includes Certificate of Inspection for traceability documentation
• Single-block package quantity for individual replacement or supplemental use

Compatibility

Designed as an individual rectangular steel gage block reference standard for use in toolroom, laboratory, and quality control applications requiring ASME Grade 0 dimensional accuracy.

Installation Notes

Gage blocks are handled and wrung by metrology technicians and quality control personnel, not installed in the traditional trade sense. Store blocks in a clean, dry environment and allow thermal stabilization before use to prevent measurement error caused by temperature differential. Clean contact faces with an approved gage block cleaning solution before wringing. Do not drop or slide blocks across abrasive surfaces, as damage to the lapped faces will affect accuracy.
