The Brown & Sharpe outside blade micrometer has a vernier scale in inch units for taking precise outside diameter (OD) measurements, and a blade anvil and spindle for measurement of groove diameter of shafts and keyways. The spindle does not rotate during adjustment, to help provide steady positioning for measurement.
The micrometer’s high-grade tool steel frame has a black enamel finish for protection and durability. The vernier scale on the thimble and sleeve is graduated to 0.001”, and has a satin chrome rust- and glare-resistant finish. The spindle and anvils are made of hardened steel for durability, and are lapped to help provide accuracy. A ring lock helps provide secure locking of the measurement position. The unit comes with a fitted wooden case for storage.
