InSize 6313-1D8 Setting Ring 1.8 Inch Diameter

The InSize 6313-1D8 is a precision setting ring designed for zero setting and calibration of inside micrometers, three-point internal micrometers, and bore gauges. With a 1.8-inch internal diameter, this setting ring provides an accurate reference standard for measuring instrument calibration in machine shops, quality control labs, and manufacturing facilities.

Key Features:

• Precision 1.8-inch internal diameter
• Made of steel construction for dimensional stability
• Includes manufacturer inspection certificate (not NIST traceable)
• Meets Class XX accuracy per ASME B89.1.6 standards
• Suitable for calibrating inside micrometers and bore gauges

Important Note: The actual size marked on the setting ring may vary slightly from the nominal 1.8-inch dimension due to manufacturing tolerances. For example, the ring may be marked 1.80008 inches to indicate the precise as-manufactured diameter. This deviation is normal and ensures the highest accuracy for calibration purposes.

Setting rings are essential tools for maintaining measurement accuracy in precision machining operations. By providing a known reference dimension, they enable operators to verify and zero their measuring instruments before use, ensuring consistent and reliable measurements throughout production runs.
