The Starrett 275-3 Toolmakers’ spring-type outside caliper opens to 3” (75 mm) with a fine adjustment and balance. It is precision made to rigid standards, for easily reproducible and accurate transfer of measurements of the internal size of an object. This caliper has round, inwardly curving legs for outside measurements and comes with a solid nut. The hardened fulcrum stud is strong to help prevent give or play in the measurement, which would reduce accuracy. The large leg bearing surfaces prevent side deflection, again to aid in accuracy. The strong, flexible bow spring has a sensitive “feel”. The centrally located adjustment rod ensures smooth action when opening and closing the caliper. Calipers measure the distance between two opposing sides of an object. They make inside, outside, depth, or step measurements, according to their type. Calipers are commonly used in architecture, metalworking, mechanical engineering, machining, manufacturing, carpentry, and medicine. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. More complex calipers use two sets of jaws instead of legs and have up to two graduated scales. Vernier, dial, and digital calipers give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw, and another jaw with a movable pointer that slides along the scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The dial caliper is used also for measuring size differential between two objects. The digital caliper takes the same sort of differential measurements as the dial caliper by zeroing the display at any point along the slide, with an LCD (replacing the dial) th...

The Starrett 460 series micrometer head has a vernier scale in inch units for taking precise measurements to 0.25”, and 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 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. 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.
