2-32"/50-800MM

These are the most popular inside micrometers because of their lightness,
ease of use, and range. They are very useful for measuring inside diameters of
cylinders and rings, measuring parallel surfaces, etc.

The desired range is obtained by assembling rods and spacing collars to the
micrometer head. Measuring rods are provided with a shoulder that is set
accurately in the micrometer head and locked in position. When assembling rods
to the A and B heads, the reading line on the micrometer head should be lined
up with the marking on each rod (except for the 2-3" and the 50-75mm rods).

Rod diameters are approximately 1/4" (6mm) on the A and B sizes, and
approximately 11/32" (8.5mm) on the C size. Each rod has individual length
adjustment for the anvil by means of special wrenches furnished.

• Measuring rods are solid and assembled on one side of the micrometer head

• Insulated rods marked with length

• Hardened and ground anvils on rods, adjustable for length. Head anvil is
hardened and ground

• Quick-reading figures – every thousandth numbered on inch reading tools

• Convenient handle is available to provide reach for use in deep holes.
Handle screws into the micrometer head in place of the dummy screw,
which is opposite a rod lock screw. Distance from the end of the handle
to the center line is 6-1/4" (158mm).
