About Starrett PT22315 Steel Contact Point For Dial Test
The Starrett ball-shaped, steel contact point has 1-64 thread size, and is designed for use with Starrett 811 series swivel-head, inch dial test indicators. Steel contact points are designed for general shop use.Dial indicators are also called dial gauges, dial calipers, and probe indicators. These precision measuring tools are used to accurately measure small linear distances and object sizes. The dial magnifies the measurement so that it can more easily be read by the human eye. Frequently used in manufacturing, laboratories, and other industrial or mechanical fields, dial indicators are used anywhere a small measurement must be found and recorded or transferred, such as checking the variation in tolerance of a workpiece. Standard dial indicators measure the displacement along the axis of the indicator. Dial test indicators are very similar to dial indicators, except that the axis of measurement is perpendicular to the axis of the indicator. Dial and dial test indicators can be analog, with a mechanical dial, or electronic, with a digital display. Some electronic models transfer the data electronically to a computer for recording and potential manipulation.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.
