Mitutoyo 611117-541 Steel Gage Block 0.17 in Grade AS-1

Product Description

The MITUTOYO 611117-541 is a rectangular steel gage block with a nominal length of 0.17 inches and an accuracy grade of AS-1. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy on the shop floor or in a metrology lab. This block is manufactured from steel and conforms to ASME standards. It ships with a Certificate of Inspection, providing documented traceability required for quality management and calibration programs. Licensed metrology technicians, machinists, and quality control professionals rely on gage blocks at this accuracy level for tight-tolerance measurement work.

This gage block is suited for use in both production and metrology environments where ASME-conforming AS-1 grade accuracy is specified. Typical applications include setting up surface plate work, calibrating micrometers and calipers, and establishing reference dimensions for precision machining setups. The 0.17-inch size makes it a useful individual block for building custom stacks or for use as a standalone reference in dimensional inspection routines.

Key Features

• Grade AS-1 accuracy conforming to ASME standards
• Rectangular steel construction for durability and wringing compatibility
• Nominal length of 0.17 inches with five-decimal precision designation
• Includes Certificate of Inspection for traceable calibration documentation
• Single-block package suitable for use individually or as part of a gage block set

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block accessories, holders, and wringing-compatible sets used in ASME-based dimensional metrology applications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality control personnel. Clean all mating surfaces thoroughly before wringing blocks together to prevent contamination and surface damage. Blocks should be stored in their protective case when not in use to prevent corrosion and wear. Avoid dropping or sliding blocks across hard surfaces, as surface damage will compromise measurement accuracy.
