Mitutoyo 177-319 Setting Ring 3.5 Inch Bore Gage Calibration Standard

The Mitutoyo 177-319 is a precision setting ring designed for accurate calibration and zeroing of measuring instruments. This 3.5-inch setting ring serves as a master reference standard for establishing baseline measurements on dial bore gages, Holtest internal micrometers, and inside micrometers.

Key Features:

• Precision ground to exact 3.5-inch internal diameter for accurate reference measurements
• Hardened and stabilized steel construction for long-term dimensional stability
• Enables quick, accurate zeroing of bore measuring instruments
• Essential calibration tool for maintaining measurement accuracy
• Compatible with Mitutoyo dial bore gages, Holtest, and inside micrometers

Setting rings are critical quality control tools that ensure your measuring instruments maintain their accuracy over time. By providing a known reference dimension, this setting ring allows you to verify and calibrate your bore gages before taking measurements, reducing measurement errors and improving quality assurance processes.
