The Fowler 52-252-211 multi-anvil EZ-Read outside micrometer has a digit display with a 0.0001" resolution, a 0 to 1" measuring range, and an interchangeable anvil for measuring tube thickness, shoulder edge distances, rivet heads, and other hard-to-measure workpieces. The flat spindle has a carbide-tipped measuring face for wear resistance and the interchangeable flat and rod-style anvils provide a variety of measuring options. The flat anvil has a thickness of 0.058" and a 1" length. The rod-style anvil has a 0.120" diameter and a 1" length. The locking lever on the spindle locks measurements in place for accurate readings. A friction thimble applies constant force for repeatability between users. Friction-style thimbles are suitable for one-handed operation and stop turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. The micrometer includes a flat anvil and rod-style anvil.

Micrometers are precision measuring instruments that use a calibrated screw to measure distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.
The Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
