Mitutoyo 611216-541 Steel Gage Block 0.65 in Grade AS-1

Product Description

The MITUTOYO 611216-541 is a rectangular steel gage block measuring 0.65 inches in overall length, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks serve as precision reference standards for calibrating measuring instruments, setting comparators, and verifying dimensional tolerances on the shop floor or in a metrology lab. This block ships with a Certificate of Inspection, confirming it has been measured and documented against traceable standards. Grade AS-1 represents a working-grade block appropriate for inspection and production use where tight dimensional accuracy is required.

This gage block is suited for use in quality control environments, tool rooms, and calibration labs in manufacturing and machining operations. Metrology technicians, quality engineers, and precision machinists rely on grade AS-1 blocks as working standards to set up measurement equipment, check part dimensions, and establish datum references. The rectangular form allows for wringing to other gage blocks when building stack combinations.

Key Features

• Grade AS-1 accuracy per ASME standards, suitable for inspection and production use
• 0.65-inch nominal length for use as a standalone reference or in wrung stacks
• Steel construction for durability in shop floor and lab environments
• Includes Certificate of Inspection for traceability documentation
• Rectangular geometry supports wringing with other gage blocks

Compatibility

Designed as an OEM-style precision reference standard compatible with standard rectangular gage block sets and accessories used in dimensional metrology applications.

Installation Notes

Gage blocks should be handled by a qualified metrology technician or quality professional familiar with proper wringing technique and block care. Clean blocks with lint-free cloths and appropriate solvents before use to prevent contamination that can affect accuracy. Store blocks in their case away from moisture and temperature extremes to prevent corrosion and dimensional drift. Do not drop, slide across abrasive surfaces, or stack without proper wringing technique.
