About Fowler 52-235-003-2 52-235 Series Advanced Design
Fowler 52-235 series Vernier-scale micrometers have a choice of measuring range and a 0.256" diameter flat anvil/spindle pair for general purpose measuring. The Vernier scale has 0.0001" graduation intervals and 0.0001" accuracy for precise readings. The anvil/spindle pair have hardened, precision-ground, and micro-lapped measuring faces with 0.00003" flatness and 0.00005" parallelism on 0 to 1" micrometers for accurate measurements. Metric equivalents inscribed on the frame in black provide quick reference. The positive locking lever on the spindle locks measurements in place for accurate readings and the zero adjustment on the sleeve ensures accurate measurements. 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 steel frame is tapered for hard-to-reach locations. The micrometer includes a wrench and fitted case. Micrometers 2" and above include a standard.

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 52-235 series outside inch micrometer Standard (for sizes 2" and above)Wrench Fitted case
