Features: High Accuracy and Precision - Spring calipers and dividers are excellent tools in providing accurate markings to maintain exact measurements from one workpiece to another. | Quality Tool - Starrett tools are durable and made from quality materials, the rugged, properly shaped legs are made of finely finished, high-grade steel. | Labor Saving - Designed for toolmakers and all good mechanics who require finer adjustment and better balance so a more sensitive feel can be obtained. The improved, firm-joint feature permits the joint to be adjusted at any desired tension. | Convenient - The actual measuring capacity is approximately one-third greater than the leg size. It has a round, adjustable leg that holds the adjustable point offset. | Meets Strong Demands - Committed in providing customers with consistent and reliable solutions, Starrett has set the standard for precision, quality and innovation. Our products are long-lasting, robust with excellent service and performance.
The Starrett 243-6 hermaphrodite caliper with bent leg has a leg length of 6” (150 mm) but opens to approximately one-third larger than the leg length. The joint allows for tension adjustment, while the tension will not change if the legs move. Hermaphrodite calipers are used to scribe lines parallel to the workpiece edge, locating and testing centers, and other layout work.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 has manufacturing facilities in Brazil, the United Kingdom, China, and other locations.
