Starrett 576, 577, 211 Rounded Anvil Micrometers

Starrett 576, 577, 211 Rounded Anvil Micrometers

0-1/2"/0-13MM; 0-1"/0-25MM

These three micrometers are all extremely useful for measuring the wall thickness of parts such as solid and split bearings, tubing, sleeves, collars, rings, various cylinders, and also measuring from the inside of a hole to an edge. All three have a rounded anvil which contacts the inside curved surface and a flat spindle for contacting the outside of the work, thus producing single point contact. This permits accurate gaging of curved surface thickness in thousandths of an inch or hundredths of a millimeter.

Rounded anvils are also available on the 222 Sheet Metal Micrometer or by special order.
