576, 577 , 211 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. Capacity • The 576 can get into holes as small as 5/16 of an inch (8mm) and measure up to 1/2 inch (13mm) • The 577 can get into holes as small as 3/8 of an inch (9.5mm) and measure up to 1 inch (25mm) • The 211 can get into holes as small as 5/8 of an inch (16mm) and measure up to 1 inch (25mm) Readability Fea tures • Starrett satin chrome finish – no glare – resists rust • Advanced sleeve design with staggered lines and distinct figures for precise and easy readability • Convenient decimal equivalents on inch tools Ease-of-Handling Fea tures • Balanced frame and thimble design ensure easy handling and readability • Gracefully designed tapered frame for narrow slots and tight places Accuracy and Long-Life Fea tures • Rigid steel frames • Extremely hard and stable one-piece spindle (the heart of our accuracy) • Quick and easy adjustment Rounded Anvil Micrometers 576, 577 and 211 Micrometers (0-1" Range) Cat.
