Fowler 52-246-025 Metric Blade Micrometer, 0-25mm Measuring Range, 0.001mm Graduation, 0.001mm Accuracy

The Fowler 52-246-025 outside micrometer has a blade-style anvil/spindle pair with a 0 to 25mm measuring range and 0.001mm graduations and is designed to measure groove diameters of shafts and workpieces with narrow or recessed features. The Vernier scale has 0.001mm graduations and an accuracy of 0.001mm for precise readings and accurate measurements. The positive locking lever on the spindle locks measurements in place for accurate readings and the zero adjustment on the sleeve ensures accurate measurements. A non-rotating spindle keeps workpieces stable during measurements. The hardened, ground, and lapped spindle thread provides smooth movement, accuracy, and long life. The ratchet-stop thimble can be used independently of the friction thimble. It provides an audible sound and stops the spindle from turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. A satin chrome finish on the thimble and sleeve helps reduce rust and glare, providing durability and long life, and microfine graduations help ensure accurate readings. The baked-enamel frame is heat-insulated to provide durability, long life, and resistance to temperature-related expansion and contraction. The micrometer includes a wrench and a fitted case.

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.
