Mul-T-Anvil Micrometers
This tool was a new development in micrometer design and patent is held
by Starrett. This micrometer will handle a wide variety of measurements
impossible to obtain with regular micrometers, such as measuring the wall
thickness of tubing, cylindrical walls from a hole or slot to an edge, many
hard-to-reach locations, and the thickness of screw heads, shoulder lengths,
etc. A most interesting feature of this tool
is that additional anvils of various shapes can be made up, and many of
these anvils do not have to be hardened for that "special job".
This micrometer can be furnished with .0001"
graduations, but we recommend .001" or 0.01 mm for easier and more
accurate readings. The Starrett Company, with our years of experience,
recommends this because the anvils on this type of tool are not backed
up by a frame as in a regular micrometer and could bend slightly. |
