Fowler 52-229-215 Digital Outside Metric Micrometer Set 0-75mm with 0.01mm Accuracy - 3-Piece Precision Measuring Tool Kit for Metalworking, Machining & Engineering Applications

Product Description

The Fowler 52-229-215 metric Vernier-scale micrometer set has a 0 to 75mm measuring range and a flat anvil/spindle pair for general purpose measuring. The Vernier scale has 0.01mm graduation intervals and an accuracy of 0.004mm for precise readings. The positive locking lever on the spindle locks measurements in place for accurate readings. Carbide-tipped measuring faces provide wear-resistance and long life. Friction thimble with 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 independent 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. The heat-insulated frame helps reduce temperature-related expansion or contraction, providing for accurate measurements. The set includes 0 to 25mm, 25 to 50mm, and 50 to 75mm micrometers, 25mm and 50mm standards, a wrench, and fitted case.SpecificationsDisplay type Vernier scale Anvil/spindle style Flat Measuring range 0 to 75mm Graduation interval 0.01mm Accuracy 0.004mm Thimble style Friction with ratchet stopMicrometers 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.What’s in the Box?Fowler 52-229-209-0 0 to 25mm outside micrometer Fowler 52-229-210-0 25 to 50mm outside micrometer and standardFowler 52-229-211-0 50 to 75mm outside micrometer and standard Wrench Fitted case
