Starrett Tubular Inside Micrometer Sets
4-32" range

The Starrett 823 Series micrometers are highly useful tools for internal
linear measurements such as measuring cylinders, rings, setting
calipers, comparing gages and measuring parallel surfaces.
The extension rods are made of steel tubing, light in weight, yet
extremely rigid. Rods are approximately 3/8" (9.5mm) diameter to
meet the requirements of mechanics who prefer this larger diameter.
By removing the hardened and ground anvil ends (end caps) of the
micrometer head, the rods may be attached to either or both ends of
the micrometer as preferred. Each rod may be individually adjusted for
wear by the hardened and ground anvil at the end.
