Summary: Checking
hole diameters.
Plug gauges are
precision measuring tools used to check the internal diameter of holes. They
are designed to verify if a hole's size is within specified tolerances. Here's
a bit more detail:
* **Function:** A
plug gauge has a cylindrical shape with very precise dimensions. It's inserted
into the hole to be measured. If the gauge fits, the hole is at or above the
minimum acceptable size. If it doesn't fit, the hole is too small.
* **Types:** Plug
gauges often come in sets with "go" and "no-go" ends. The
"go" end is sized to the minimum acceptable diameter, and the
"no-go" end is sized to the maximum. This allows for a quick check of
whether the hole is within the tolerance range.
* **Use:** Plug gauges are essential in manufacturing and quality control to ensure that parts are interchangeable and will fit together correctly.
