Mitutoyo 611154-541 Steel Gage Block 0.114 in Grade AS-1

Product Description

The MITUTOYO 611154-541 is a rectangular steel gage block measuring 0.114 inches, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks are precision-ground, hardened steel reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in quality control environments. Grade AS-1 represents a high level of dimensional accuracy, making this block suitable for demanding inspection and calibration applications in machine shops, tool rooms, and metrology labs. A Certificate of Inspection is included with each unit, providing documented traceability for quality assurance programs.

This gage block is intended for use in precision metrology applications where verified dimensional reference standards are required. Typical users include machinists, quality control technicians, and metrologists working in manufacturing, aerospace, automotive, and general industrial environments. The 0.114-inch size makes it a specific-value block suited for building gage block stacks or serving as a standalone reference standard for calibration setups.

Compatibility

Designed as an ASME-compliant Grade AS-1 rectangular steel gage block suitable for use with standard gage block sets and accessories in precision metrology and calibration applications.

Installation Notes

Gage blocks should be handled by qualified metrology or quality control personnel. Clean all mating surfaces before wringing blocks together to prevent surface damage and measurement error. Store blocks in their protective case away from temperature extremes and moisture to maintain calibration integrity. Never drop or stack gage blocks without proper technique, as surface damage will compromise dimensional accuracy.
