What type of gauge is capable of detecting variations in a hole's diameter when fitted with a custom gauge head?

The federal gauge is specifically designed for precision measurements of hole diameters and can easily detect small variations in size. When fitted with a custom gauge head, it can provide accurate readings by making contact with the inner surface of a hole. These gauges typically use a series of interchangeable heads and measuring elements that can be tailored to specific applications and measurements, making them particularly versatile in situations where precise hole dimensions are critical.

Unlike dial gauges or digital gauges, which may be more suited for linear measurements or less specialized applications, the federal gauge’s design is optimized for measuring internal diameters with a high degree of accuracy, especially in manufacturing and assembly processes in the aerospace industry. This capability makes it an essential tool for mechanics who need to ensure that components fit correctly and function as required in high-stakes environments.
