• Non-rotating spindle helps prevent wear to the workpiece
• Vernier scale in inch units for taking precise measurements to 1"
• Knurled ring-type lock nut to hold measurements in place
• Satin chrome finish helps resist rust and reduce glare
• Micro-lapped measuring face helps provide accuracy

The Starrett 262 series long range micrometer head has a non-rotating spindle that helps prevent wear to the workpiece and a Vernier scale in inch units for taking precise measurements to 1”. It also has a knurled ring-type lock nut to hold measurements in place. The micrometer has a plain stem for mounting in a fixture with a split-body clamp or setscrew. The Vernier scale is graduated to 0.001” and has a satin chrome rust- and glare-resistant finish. The spindle is made of hardened steel to help provide durability with a flat measuring face suitable for measurement or use as a stop and is micro-lapped to help provide accuracy. Micrometers are precision measuring instruments that use a calibrated screw to measure small 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 callipers 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. Micrometer heads are for mounting in fixtures, where they are typically used for measurement or as stops or feeds. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
