Mitutoyo 611206-541 Steel Gage Block 6 in Grade AS-1

Product Description

The MITUTOYO 611206-541 is a rectangular steel gage block ground and lapped to a nominal length of 6.00000 inches at Grade AS-1 accuracy. Gage blocks serve as primary length reference standards used to calibrate measuring instruments, verify machine setups, and establish precise dimensional references on the shop floor or in the metrology lab. This block ships with a Certificate of Inspection, confirming it meets ASME dimensional and tolerance requirements for Grade AS-1. Metrologists, quality technicians, and precision machinists rely on Grade AS-1 blocks for applications where tight dimensional traceability is required.

This gage block is suited for use in calibration labs, tool rooms, and precision manufacturing environments. It functions as a standalone reference standard or as part of a gage block set. Typical applications include instrument calibration, surface plate layout work, go/no-go gauge verification, and CMM reference checks. The 6-inch nominal size makes it appropriate for calibrating calipers, height gauges, and other long-range measuring instruments.

Key Features

• Nominal length of 6.00000 inches ground to Grade AS-1 tolerance per ASME standards
• Steel construction provides durability and long-term dimensional stability
• Includes Certificate of Inspection for traceable quality documentation
• Rectangular form allows wringing to other gage blocks for combination lengths
• Complies with ASME gage block standards for accuracy grade classification

Compatibility

Designed as an OEM-style reference standard compatible with standard gage block sets and accessories that accept rectangular-form steel gage blocks in the 6-inch nominal size range.

Installation Notes

Gage blocks are handled and stored by metrology technicians and precision inspection professionals. Clean block surfaces with an appropriate gage block cleaning solution before and after use to prevent corrosion and contamination. When wringing blocks together, use a light sliding motion rather than forcing contact to avoid surface damage. Store in the provided case in a temperature-stable environment to maintain dimensional accuracy.
