Mitutoyo 611199-541 Steel Gage Block 0.9 in Grade AS-1

Product Description

The MITUTOYO 611199-541 is a rectangular steel gage block measuring 0.9 inches in nominal length, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks are precision reference standards used to calibrate measuring instruments, verify dimensional accuracy, and set comparators in metrology and quality control environments. This block ships with a Certificate of Inspection, confirming it meets the stated tolerance grade. Grade AS-1 represents a calibration-grade standard suitable for laboratory and inspection room use where tight dimensional traceability is required.

This gage block is suited for use in machine shops, quality labs, toolrooms, and manufacturing inspection stations. It serves as a reference standard for calibrating micrometers, dial indicators, height gages, and other precision measuring tools. Typical users include metrology technicians, quality control inspectors, and tool and die professionals who require traceable dimensional references for inspection and setup work.

Key Features

• Grade AS-1 accuracy per ASME standards — suitable for calibration and inspection room use
• Nominal size of 0.9 inches (0.90000 decimal inches to five decimal places)
• Steel construction for durability and dimensional stability
• Includes Certificate of Inspection for traceability documentation
• Rectangular block form for wringing and stacking with other gage blocks

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block sets and accessories that accept rectangular-form steel gage blocks per ASME specifications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality control professionals. Keep block surfaces clean and free of burrs before wringing or stacking. Store in the supplied case when not in use to prevent corrosion and surface damage. Follow facility calibration procedures and applicable ASME B89 standards for proper use and recalibration intervals.
