  • Flush pins are typically made of hardened tool steel and have a stepped or ground shoulder on the end.
  • The shoulder is the reference surface for the measurement.
  • To use a flush pin, the pin is inserted into the hole or feature to be measured.
  • The shoulder on the pin should rest flush against the top surface of the workpiece.
  • The depth of the hole or feature is then measured from the shoulder of the pin to the top surface of the workpiece.
  • Flush pins are used in a variety of industries, including manufacturing, automotive, aerospace, and electronics.
  • They are particularly useful for measuring the depth of blind holes and holes in hard-to-reach locations.

Here are some specific examples of how flush pins are used in measurement:

  • Measuring the depth of a drilled hole in a machine part
  • Measuring the depth of a blind hole in a casting
  • Measuring the depth of a counterbore in a machined surface
  • Measuring the depth of a port in a cylinder
  • Measuring the depth of a slot in a milled surface

Here are some of the benefits of using flush pins:

  • They are accurate and reliable.
  • They are easy to use.
  • They are durable and can withstand repeated use.
  • They are available in a variety of sizes to accommodate a wide range of measurement applications.

Overall, flush pins are an essential tool for anyone who needs to measure the depth of holes, steps, and counterbores.
