Product details
A plug gauge, similar to a pin gauge, is a precision measurement tool used to check the dimensions of holes. It consists of a cylindrical rod or plug with a precisely defined diameter, made from materials such as hardened and ground steel. Plug gauges are used to verify the internal dimensions of holes, ensuring they meet specified tolerances. Here's how plug gauges are typically used: Selection of Plug: The operator selects a plug gauge with a diameter that matches the nominal size of the hole to be measured. Insertion into the Hole: The plug gauge is inserted into the hole being measured. Checking Fit: The fit of the plug gauge inside the hole is assessed. If the plug goes in easily and fits snugly, the hole is within tolerance. If there's resistance or if the plug doesn't fit at all, it indicates that the hole is smaller than the plug diameter. Verification of Tolerance: The fit of the plug gauge helps determine whether the hole falls within the acceptable tolerance range. Plug gauges are essential tools in quality control and precision machining processes. They are commonly used in industries such as manufacturing, aerospace, and automotive, where accurate hole dimensions are critical for the proper functioning of components. Like pin gauges, plug gauges come in sets with plugs of various diameters to cover a range of hole sizes.
