Mitutoyo 611115-541 Steel Gage Block 0.15 in Grade AS-1

Product Description

The MITUTOYO 611115-541 is a rectangular steel gage block sized at 0.15 inches, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor and in metrology labs. This block ships with a Certificate of Inspection, confirming it has been measured and certified to Grade AS-1 tolerances before leaving the factory. Grade AS-1 represents a high level of dimensional accuracy suitable for demanding inspection and calibration work in production and laboratory environments.

This gage block is suited for metrology technicians, quality control inspectors, and tool room machinists who require traceable dimensional references. Typical applications include setting dial indicators, height gages, and optical comparators, as well as verifying the accuracy of calipers and micrometers. The rectangular form allows the block to be wrung to other gage blocks in a set or used individually as a standalone reference standard for the 0.15-inch nominal size.

Key Features

• Grade AS-1 accuracy per ASME standards for high-precision calibration and inspection use
• Steel construction provides durability and stability across typical shop and lab temperature ranges
• Nominal size of 0.15 inches with five-decimal precision designation (0.15000 inches)
• Includes Certificate of Inspection for traceability documentation
• Rectangular form compatible with wringing to other gage blocks for stacked measurements

Compatibility

Designed as an OEM-style rectangular gage block reference standard for use with standard gage block accessories, holders, and wringing sets conforming to ASME gage block specifications.

Installation Notes

Gage blocks are handled by metrology technicians and quality control personnel, not typically installed with tools. Blocks should be cleaned with a lint-free cloth and appropriate solvent before and after use to prevent corrosion and maintain wringing surfaces. Store in the supplied case or protective container when not in use to avoid surface damage. Follow your facility calibration procedures and applicable ASME standards when using gage blocks as reference standards.
