InSize 6313-3 Precision Setting Ring 3.0 Inch Diameter

The InSize 6313-3 is a precision calibration setting ring used for calibrating inside micrometers, three point internal micrometers, and bore gages. This 3.0 inch diameter setting ring provides accurate reference standards for zero-setting precision measuring instruments in machine shops, quality control labs, and manufacturing facilities.

Key Features:

• 3.0 inch internal diameter calibration standard
• Accuracy of +/- .0001 inch (Class X accuracy)
• Deviation of +/- .00012 inch for sizes .1180-3.9370 inches
• Meets ANSI/ASME B89 specifications
• Supplied in fitted storage case for protection

Setting rings are used for zero setting of inside micrometers, three points internal micrometers and bore gages. The deviation is the difference between the ordered size and the size marked on the setting ring when supplied. This precision measuring standard ensures your bore gages and internal measuring tools maintain accuracy for critical dimensional inspection work.
