The Moore & Wright 965m micrometer is made of metal. The base of a micrometer is in the shape of the letter C, at its upper end is a stationary anvil, at the other end a pivot that moves in or out through the other end of the C frame.

The anvil acts as one grip point for measuring objects. This is the strong and stable measuring point of a micrometer.

A long cylindrical shaft that is installed through all the other parts and moves with a ratchet at its lower end. When we turn the ratchet clockwise or counterclockwise, the shaft slides out or in to adjust it to measure the size of the object that is currently between the anvil and the shaft. In the lower part of the "C" there is a ring used to lock the axis so that during the measurement the axis will not change its position.

In the lower part above the axis there are scales for measuring the thickness of the object measured in different measurement units.
