Mitutoyo 611126-541 Steel Gage Block 0.1006 in Grade AS-1

Product Description

The MITUTOYO 611126-541 is a rectangular steel gage block ground to a nominal size of 0.1006 inches and certified to ASME Grade AS-1 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, verify machine tool settings, and establish dimensional references on the shop floor. This block ships with a Certificate of Inspection, providing documented traceability for quality systems. Grade AS-1 designates a workshop-grade block suited for production environments where reliable, repeatable length references are required. Machinists, metrologists, and toolroom technicians are the primary users of this type of precision reference standard.

This gage block is used wherever a precise 0.1006-inch length reference is needed, including calibration labs, machine tool setups, inspection departments, and production floor applications. It is appropriate for both in-process inspection work and for setting height gages, micrometers, and comparators. The ASME standard governs its dimensional and surface finish requirements, making it suitable for use in quality systems that require standards-body compliance. Individual blocks can be wrung together with other gage blocks from a set to build up composite dimensions.

Key Features

• Grade AS-1 accuracy per ASME standards for workshop and production use
• 0.1006-inch nominal size with five-decimal precision
• Steel construction provides durability and wear resistance for repeated use
• Includes Certificate of Inspection for quality system traceability
• Rectangular geometry supports wringing with other gage blocks to build composite dimensions

Compatibility

Designed as a standalone precision length reference conforming to ASME gage block standards. Compatible with standard gage block accessories and wringable with other rectangular steel gage blocks for composite setups.

Installation Notes

Gage blocks require no mechanical installation but should be handled and stored following standard metrology practices. Clean contact surfaces with a lint-free cloth and appropriate solvent before use to prevent contamination that can affect wringing and accuracy. Avoid dropping or stacking with non-precision items, as surface damage will compromise the reference value. A licensed metrologist or calibration technician should perform periodic recalibration in accordance with the applicable quality management system requirements.
