0.2 to 0.3 Inch Measurement, 1-3/16 Inch Gage Depth, Small Hole Gage MPN:31-442-7

The small hole gage is a precision tool used for measuring the inside diameter of holes, recesses, or rings with diameters ranging from 0.2 to 0.3 inches and depths of 1-3/16 inches. This gage consists of an anvil with a cylindrical face ground to fit precisely into the hole being measured, a small plug attached to the anvil by a spring, and a threaded rod that pushes the plug against the anvil to engage the internal diameter. The clearance between the anvil and the cylindrical surface of the plug is used to measure the inside diameter of the hole. The anvil has a graduated scale marked in hundredths and thousandths of an inch, allowing for precise measurements down to 0.001 inches. Small hole gages are commonly used in industries such as machining, manufacturing, toolmaking, and precision engineering where accurate measurements of small diameters are required. They can also be used in quality control or inspection departments to ensure components meet dimensional specifications before assembly or shipment.
