Outer diameter micrometer the external
dimensions measuring instruments, measure the distance between the two sides of
the square frame by use of helix principle. Outer diameter micrometer is mainly
used for measuring a variety of external dimensions.
Diameter micrometer dividing value is

4. Locking device can be passive
measurement of micro-screw back and forth. Relax to the right and lock to the
left. (See instructions for use Figure 3)
