Starrett 724 Tubular Bow Micrometers with Interchangeable Anvils
The Starrett 724 Tubular Bow Micrometers are made for more precise measurements on large outside dimensions. They provide perfect balance, sensitive feel, ease of handling, and less measuring effort due to their advanced tubular design. Frames are built of special steel formed to exacting tubular design specifications and welded by a carefully controlled process. This produces a hollow tubular frame of the lightest weight, extreme rigidity, and a standard coefficient of expansion.
Because of the interchangeable anvils, the 724 is well suited for diversified gaging and provides a wide range of measurement in steps of 1 inch. The micrometer head has a larger diameter anvil and spindle at .300in (7.6mm). This provides greater balance and a larger bearing surface on the threads.
NOTE: It is recommended that these micrometers be checked with standards in the approximate position (vertical or horizontal) that they will be used. We do not recommend .0001in or 0.001mm readings on these micrometers.
