Mitutoyo 611125-541 Steel Gage Block 0.1005 in Grade AS-1

Product Description

The MITUTOYO 611125-541 is a rectangular steel gage block measuring 0.10050 inches, 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 quality control environments. This block includes a Certificate of Inspection, confirming it has been verified against traceable standards. Grade AS-1 represents a high-accuracy classification under ASME B89.1.9, making it appropriate for inspection-grade applications where tight dimensional verification is required. Metrology technicians, tool room machinists, and quality assurance personnel are the primary users.

This gage block is suited for use in inspection rooms, machine shops, and tool rooms where precise linear measurement references are needed. It functions as a standalone reference block or as part of a gage block set for building up specific dimensions. Typical applications include setting dial indicators, digital calipers, and height gages to a known reference, as well as qualifying fixtures and incoming inspection of machined components.

Key Features

• Nominal size of 0.10050 inches for precise linear reference
• Grade AS-1 accuracy per ASME B89.1.9 standard
• Steel construction for durability and wear resistance
• Includes Certificate of Inspection with traceable verification
• Rectangular form compatible with standard wringing and block-set use

Compatibility

Designed as an OEM-style precision reference standard compatible with standard rectangular gage block accessories, holders, and wringing fixtures used in ASME-compliant metrology setups.

Installation Notes

Gage blocks are handled by metrology technicians and tool room personnel. Before use, clean contact faces thoroughly with an appropriate solvent and lint-free cloth to remove oils and debris that can affect accuracy. Wring blocks together with a slow, overlapping sliding motion rather than snapping them together to avoid surface damage. Store blocks in their protective case when not in use to prevent corrosion and surface wear.
