Starrett T436.1XFL-2 Outside Micrometre, Friction Thimble, Lock Nut, Carbide Faces, 1-2" Range, 0.0001" Graduation, +/-0.00005" Accuracy

The rigid 436.1 series outside of micrometers has a Vernier scale in tariff units for precise measurements of the outer diameter (OD), a conical frame for measuring narrow slots and narrower places as well as a knurled friction chocolate, which allows a quick setting option. The steel frame of the micrometer has a baked enamel surface for protection and durability. The Vernier scale at festuring hat and sleeve is graded to 0.0001 inches with a rust and glare-resistant surface made of satin chrome. The spindle and anvil have flat, micro-grown measuring surfaces for accuracy and are equipped for wear resistance with carbide fittance. A knurled ring locking nut contributes to the safe locking of the measuring position. Micrometers are precision meters that measure small distances with a calibrated snail. These measurements are translated into large rotations of the screw, which can then be read from a scale or dial. Micrometers are typically used in manufacturing, machining and mechanical engineering. There are three types of micrometers: outside, inside and depth. Outside micrometers can also be referred to as micrometer saddles and are used to measure the length, width or outer diameter of an object. Inner micrometers are typically used to measure the inner diameter as in a hole. Depth micrometer measure the height or depth of a shape that has a step, a groove or a slot. The L.S. StarRett Company produces precision measuring tools, measuring and testing equipment as well as saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
