Fowler Full Warranty Outside Inch Micrometer, 52-253-004-1, Ratchet Stop Thimble, 3-4" Measuring Range, 0.0002" Accuracy, 0.001" Graduation

Description

The Fowler 52-253-004-1 Vernier-scale micrometer has a 0.256" diameter flat anvil/spindle pair for general purpose measuring. The Vernier scale has 0.001" graduation intervals and 0.0002" accuracy for precise and accurate readings. The carbide-tipped anvil/spindle pair have hardened, precision-ground, and micro-lapped measuring faces with 0.00003" flatness and 0.00012" parallelism for accurate measurements. The positive locking lever on the spindle locks measurements in place for accurate readings. Ratchet stop 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 ratchet stop thimble can be used independently of the 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 long life, and microfine graduations help ensure accurate readings. The micrometer includes a wrench and a fitted case. Micrometers 2" and above include a standard. This product has a 1 year warranty offered by Fowler High Precision. If you experience any problem contact Fowler directly for warranty claims.

Specifications

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.

Fowler, an American 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.
