Starrett 274-6 Toolmakers' Inside Caliper, Solid Nut, 6"/150mm Leg Length Item Description The Starrett 274-6 Toolmakers’ spring-type inside caliper opens to 6” (150 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, outwardly curving legs for inside 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) that displays a single, easily read value in both English and metric units. Some digital calipers can hold data readings between measurements and send them to data collection devices. The L. S. Starrett Company was founded in 1880, originally manufacturing bench vises, squares, and other tools. They acquired other companies throughout the years, expanding their services into making precision measurement instruments and tools, such as calipers, micrometers, saw blades, and gauges. Starrett is headquartered in Athol, Massachusetts and they have manufacturing facilities in Brazil, the United Kingdom, China, and other locations.
