Mitutoyo 611202-541 Rectangular Steel Gage Block 2 in AS-1

Product Description

The MITUTOYO 611202-541 is a 2-inch rectangular steel gage block used as a precision length reference in dimensional measurement and calibration work. Manufactured to ASME AS-1 accuracy grade, it delivers the tight tolerances required for tool room inspection, surface plate work, and calibration of measuring instruments. Each block ships with a Certificate of Inspection, confirming it has been verified against traceable standards. Gage blocks are fundamental reference tools in any precision metrology setup, and this unit is built from steel for durability and long-term dimensional stability.

This gage block is suited for use in tool rooms, quality control labs, and production measurement environments where a reliable length reference is required. Typical applications include setting comparators, verifying micrometers and calipers, and establishing reference dimensions during inspection. It is appropriate for both industrial and precision trade settings where ASME-grade measurement standards are required.

Key Features

• ASME AS-1 accuracy grade for high-precision dimensional reference
• Rectangular steel construction for durability and long-term stability
• Nominal length of 2 inches
• Includes Certificate of Inspection with traceable verification
• Packaged individually for single-block calibration and reference tasks

Compatibility

Designed as a general-purpose precision length reference block compatible with standard gage block sets and accessories conforming to ASME B89.1.9 or equivalent dimensional metrology standards.

Installation Notes

Gage blocks are handled and set up by metrology technicians, quality control personnel, or precision machinists rather than installed in a conventional sense. Always clean the measuring faces thoroughly before wringing or use to avoid contamination that can affect accuracy. Store blocks in a protective case away from temperature extremes and humidity to preserve surface quality and dimensional integrity. Follow applicable ASME or facility calibration procedures when using this block as a measurement reference.
