Mitutoyo 611152-541 Steel Gage Block 0.112 in Grade AS-1

Product Description

The MITUTOYO 611152-541 is a rectangular steel gage block measuring 0.112 inches in overall length, manufactured to ASME Grade AS-1 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, verify dimensional tolerances, and establish traceable length references in metrology, machining, and quality control environments. Each block ships with a Certificate of Inspection confirming conformance to stated accuracy. Grade AS-1 represents a high-accuracy classification under ASME B89.1.9, making this block appropriate for laboratory, toolroom, and production floor calibration work performed by metrology technicians, quality engineers, and precision machinists.

This gage block is suited for use in dimensional metrology applications including instrument calibration, gauge verification, and setup of precision machining operations. Its rectangular steel construction makes it compatible with standard wringing techniques used to combine multiple blocks into a composite stack dimension. Typical environments include QC labs, tool and die shops, and precision manufacturing facilities where traceable dimensional standards are required.

Key Features

• Grade AS-1 accuracy per ASME B89.1.9 for high-precision reference work
• 0.112-inch nominal size with five-decimal precision designation
• Steel construction supports standard wringing for block stacking
• Includes Certificate of Inspection for traceability documentation
• Rectangular form for stable contact surface in calibration setups

Compatibility

Designed as an individual gage block for use as a standalone reference standard or as part of a gage block set in any application requiring ASME-compliant Grade AS-1 steel reference blocks.

Installation Notes

Gage blocks are handled and stored by metrology technicians or quality personnel, not installed in the traditional sense. Blocks should be cleaned with an appropriate solvent and lint-free cloth before use to remove oils and debris that affect accuracy. Wringing of blocks requires clean, flat surfaces and light lateral pressure — do not use force or impact. Store blocks in their protective case away from temperature extremes to maintain dimensional stability.
