724 Tubular Bow Type Micrometers with Interchangeable Anvils 12-60"/300 -1500MM These 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 or 25mm. The micrometer head has a larger diameter anvil and spindle at .300" (7.6mm). This provides greater balance and larger bearing surface on the threads. 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 • Large thimble diameter with distinct figures Ease-of-Handling Fea tures • Balanced frame and thimble design for easy handling and better readability • Ring-type knurled lock nut for quick and sure locking • Hollow tubular frame design combining lightest possible weight with rigidity Accuracy and Long-Life Fea tures • Extremely hard and stable one-piece spindle (the heart of our accuracy) • Standards with insulated grips • 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 .0001" or 0.001mm readings on these micrometers.Larger sizes, carbide faces and ratchet stop are available on special order.
