Mitutoyo 611105-541 Steel Gage Block 0.05 in Grade AS-1

Product Description

The MITUTOYO 611105-541 is a rectangular steel gage block measuring 0.05 inches, manufactured to ASME Grade AS-1 accuracy. Gage blocks are precision-ground reference standards used to calibrate measurement equipment, set comparators, and verify dimensional accuracy in machine shops, metrology labs, and quality control environments. This block ships with a Certificate of Inspection, confirming it meets the stated accuracy grade. Grade AS-1 represents a high level of dimensional precision, making this block appropriate for exacting calibration and inspection work performed by metrology technicians and quality assurance professionals.

This gage block is suited for use in tool rooms, manufacturing facilities, and calibration labs where traceable dimensional references are required. The 0.05-inch size fills a common calibration increment used when building block stacks to achieve specific reference dimensions. It is appropriate for both bench-level calibration setups and in-process inspection stations across a range of metalworking and precision manufacturing applications.

Key Features

• Grade AS-1 accuracy per ASME standards for high-precision dimensional reference
• Steel construction for durability and resistance to wear in shop environments
• 0.05-inch nominal length for use in standard gage block stacking sets
• Includes Certificate of Inspection for traceability documentation
• Rectangular form factor compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style precision reference standard for use with standard rectangular gage block accessories, holders, and wringing sets in metrology and quality control applications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality control personnel. Before use, clean block surfaces with an appropriate solvent to remove oils and contaminants that affect wringing and accuracy. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Avoid contact with abrasive surfaces and handle with clean, lint-free gloves or tools to preserve surface finish and measurement integrity.
