Mitutoyo 611611-531 Steel Gage Block 1 Mm Grade 0

Product Description

The MITUTOYO 611611-531 is a rectangular steel gage block with a nominal size of 1 mm and an Accuracy Grade 0 rating. Gage blocks are precision-ground, hardened steel reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional accuracy on the shop floor or in the metrology lab. Grade 0 represents a high level of dimensional accuracy suitable for calibration and inspection applications where tight tolerances are required. Each block includes a Certificate of Inspection. It is primarily used by quality control technicians, metrologists, and precision machinists who require traceable dimensional references.

This gage block is suited for use in inspection rooms, tool rooms, and manufacturing environments where dimensional verification of machined parts, fixtures, and measuring equipment is performed. It functions as a standalone reference standard or as part of a gage block set. The block conforms to ASME standards, making it appropriate for facilities that follow standard metrology practices in both production and laboratory settings.

Key Features

• Grade 0 accuracy rating per ASME standards for high-precision calibration and inspection use
• Rectangular form factor in hardened steel for durability and long-term dimensional stability
• Nominal size of 1 mm for use as a precise reference standard
• Includes Certificate of Inspection for traceability documentation
• ASME-compliant construction supports use in regulated inspection and quality environments

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block accessory sets and holders intended for rectangular-style gage blocks conforming to ASME specifications.

Installation Notes

Gage blocks are handled and stored by metrologists and quality technicians rather than installed in a traditional sense. Blocks should be wrung together or used with appropriate holders on a clean, stable surface. Handle with clean, lint-free gloves to prevent corrosion from skin contact. Store in the provided case or a protected environment to maintain surface integrity and dimensional accuracy.
