Description

The Fowler 52-226-801-1 digit micrometer has a 0-1″ measuring range and a 60-degree pointed anvil/spindle pair for measuring hard-to-reach areas including thread accuracy in screw-cutting operations, small flutes, recesses, grooved trolley wires, and keyways. The digit display has 0.001″ graduation intervals and Vernier scale has 0.0001″ graduation intervals and an overall accuracy of 0.00016″ for precise readings. Microfine graduations on a satin chrome finish provide clear reading. The positive locking nut on the spindle locks measurements in place for accurate readings. A zero adjustment on the sleeve ensures accurate measurements. The conical anvil and spindle have a hardened and precision ground micro-lapped finish with a 0.012″ radius curvature at the extremity and a 0.21″ length for wear resistance and long life. The spindle thread is hardened, ground, and lapped to provide smooth movement, accuracy, and long life. The ratchet-stop thimble provides an audible sound and stops turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. The grey baked-enamel frame provides durability.

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.
