Brown & Sharpe 599-591-5 Telescoping Gage, 2-1/8" - 3-1/2"

The Brown & Sharpe 599-591 series telescoping gage is used for measuring the internal diameter of a bore or the width of a groove. A knurled lock retains setting of the measurement arm for sizing with a micrometer or caliper. The satin chrome finish resists rust and is glare-free. It comes assembled with a handle.

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.

Brown & Sharpe manufactures precision measuring equipment and metrology hand tools. The company, founded in 1833, is headquartered in North Kingstown, RI.
