Description

The Starrett depth gauge base is available in a 4", 6", or 8" length and has one to three collet mounting hole locations for use with Starrett 648 series depth gauges. The supplied mounting collet holds a depth gauge (sold separately) securely. The base is 3/4" wide and has tapped mounting holes to fit 3/8" (9.5mm) gauge stem diameters. It is made of hardened steel for durability and accurate measurements, and is suitable for precise measurement in a variety of manufacturing, machining, and mechanical engineering applications. Depth gauges are precision measuring instruments used to determine the depth of any shape that has a step, groove, or slot. These gauges often take the form of sliders that travel on a measuring beam or rods, are moved to position by hand, and then adjusted with a calibrated screw. The base of the gauge rests at the top of the shape whose recession is to be measured, while the beam or rods extend to the bottom of the recession to determine the measurement. Gauge position is read from a graduated scale, dial, counters, or an electronic display. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.
