Fowler 52-219-091 Steel EZ-Read Digit Thread Micrometer, 0-1" Measuring Range, 0.0001" Graduation, 0.0002 Accuracy

The Fowler 52-219-091 EZ-Read digit micrometer has a 0 to 1" measuring range and a 60-degree anvil/spindle pair to measure the pitch diameter of 60-degree unified (UNF) threads from 64 to 5 threads per inch (TPI). The digit display has 0.0001" graduation intervals and an accuracy of 0.0002" for precise readings. The adjustable anvil and spindle with locking levers are made from hardened and ground high-grade steel for durability and long life. Non-rotating spindle provides stability when the spindle comes into contact with the workpiece, and the spindle-locking lever locks the measurement in place for accurate readings. A friction thimble provides smooth and quiet operations, and is suitable for one-handed operation. Friction-style thimbles stop turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. The micrometer includes five interchangeable anvil sets 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.
