Mitutoyo 611121-541 Steel Gage Block 0.1001 in Grade AS-1

Product Description

The MITUTOYO 611121-541 is a rectangular steel gage block measuring 0.1001 inches in overall length, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks serve as primary length reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in precision machining and inspection environments. Each block includes a Certificate of Inspection, confirming it has been measured and verified against traceable standards. Grade AS-1 represents a high-accuracy classification suitable for tool room and inspection applications. Licensed metrology technicians, quality control inspectors, and precision machinists are the primary users of this type of reference standard.

This gage block is suited for use in tool rooms, inspection departments, and manufacturing facilities where accurate length reference is required. It functions as a standalone block for setting instruments or as part of a larger gage block set for building up specific dimensions. Applications include surface plate work, comparator calibration, and machine setup verification in both production and quality assurance settings. The 0.1001-inch size is a common increment used in combination sets to achieve precise stack-up dimensions.

Key Features

• Grade AS-1 accuracy per ASME standards for reliable dimensional reference
• Rectangular steel construction provides durability and wringing compatibility
• 0.1001-inch nominal size for use in combination gage block sets
• Includes Certificate of Inspection for traceability documentation
• Single-piece packaging suitable for individual replacement or supplemental use

Compatibility

Designed as an OEM-style rectangular gage block compatible with standard wringing sets and gage block accessories conforming to ASME B89.1.9 specifications for Grade AS-1 steel gage blocks.

Installation Notes

Gage blocks are handled and stored by metrology or quality control personnel, not installed in the conventional trade sense. Before use, clean all mating surfaces with an appropriate gage block cleaning solution to remove oils and debris. Wring blocks together using a clean, flat surface and controlled lateral sliding motion to achieve adhesion. Store blocks in their protective case when not in use to prevent corrosion and surface damage on the precision-lapped faces.
