For anyone who works with precision measurements, the difference between success and failure often comes down to micrometers. That's why machinists, engineers, and quality control professionals rely on tools they can count on without question. The Mitutoyo 177-290 setting ring delivers exactly that – uncompromising precision in a compact, durable package.
At 40mm with a 15mm width and 71mm outside diameter, this setting ring isn't just another measuring tool – it's your foundation for accuracy. The +/-1.5 micrometer tolerance means you're working within the tightest tolerances, whether you're calibrating dial indicators, checking bore diameters, or verifying the accuracy of other measuring instruments. When you're working on aerospace components, medical devices, or high-performance automotive parts, that level of precision isn't just helpful – it's essential.

The robust construction ensures it won't bend or wear under normal handling, making it a long-term investment in your measurement toolkit. Unlike cheaper alternatives that might need frequent recalibration, this setting ring provides consistent performance you can trust for years to come.
From machine shops to quality labs, this setting ring finds its home wherever precision matters. Use it to set up coordinate measuring machines, verify gage accuracy, or as a master reference for comparative measurements. The 40mm size makes it ideal for medium-sized workpieces while still being manageable enough for detailed bench work. Whether you're training new technicians or conducting final inspections, this ring becomes the standard against which all other measurements are judged.
