Fowler 52-229-214-0 Economy Outside Micrometer Set with 0–4" Range (Set of 4)

Fowler 52-229 series outside Vernier-scale micrometers have a choice of measuring range and a flat anvil/spindle pair for general purpose measuring. The Vernier scale has 0.0001" microfine graduation intervals on a satin chrome finish for precise readings. The positive locking nut on the spindle locks measurements in place for accurate readings and the zero adjustment on the sleeve ensures accurate measurements. The anvil/spindle pair have 0.256" diameter, hardened, precision-ground, and micro-lapped carbide measuring faces with 0.00003" flatness and 0.00005" parallelism on 0 to 1".   The ratchet thimble is suitable for one-handed operation and stops turning when the spindle comes into contact with the workpiece, providing constant force for consistent measurements between operators. The ratchet-stop 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. The heat-insulated frame helps reduce temperature-related expansion or contraction, providing accurate measurements, and protects the micrometer frame from heat. The set includes 0 to 1", 1 to 2", 2 to 3" and 3 to 4”micrometers, 1", 2", and 3” standards, a wrench, and a fitted case. This product has a 1 year warranty offered by Fowler High Precision.

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.
