Countersink Gages

Quick Answer

A countersink gage is a precision instrument used to measure the diameter and angle of a countersunk hole — verifying that the countersink matches the specified included angle and is sized correctly to seat a flathead fastener flush with the workpiece surface. Countersink gages are available in dial and electronic (SPC) configurations across a range of included angles including 82°, 90°, 100°, 110°, and 120°.
