Micrometers

Micrometers are precision measuring instruments used to measure the linear dimensions of small objects. They are typically used in the manufacturing and engineering industries, as well as in the automotive and aerospace industries.

Micrometers are available in a variety of styles, including:

• Outside micrometers are used to measure the outside diameter of a cylindrical object.
• Inside micrometers are used to measure the inside diameter of a cylindrical object.
• Depth micrometers are used to measure the depth of a hole or slot.
• Thread micrometers are used to measure the pitch of a thread.

Micrometers are typically made of hardened steel or stainless steel, and they feature a calibrated scale that is divided into small increments. The most common type of micrometer scale is the vernier scale, which consists of a long, graduated scale and a shorter, movable scale. The movable scale is used to make fine adjustments to the measurement.

Micrometers are used by placing the object to be measured between the anvil and the spindle. The spindle is then rotated until the object is firmly held between the two jaws. The measurement is then read from the scale.

Micrometers are accurate measuring instruments, but they require careful handling to avoid damage. It is important to clean the micrometer before and after each use, and to store it in a protective case.
