In comparison to the cylindrical gauges with handles, M+T single-ended plug gauges have a shorter measuring cylinder and are a cost-effective alternative to standard cylindrical gauges with or without a handle for many measuring and testing tasks where a long meas-uring cylinder is not required. They are suitable for determining diameters and clearances of small and minute boreholes. They also serve to measure grooves and other inside dimensions. In addition, they can be used as precise setting standards for measuring equipment with displays and for calibrating devices.
An M+T single-ended plug gauge is distinguished by its particularly cost-effective price-performance ratio whilst also providing the usual benefits of M+T products with regard to precision, reliability, user-friendliness and sturdiness.

Pin gauges are precision cylindrical pins designed to inspect the inner diameters of a workpiece. They function similarly to Go and No-Go gauges, helping to determine if a hole falls within specified tolerances. Pin gauges are also used to check for geometric deviations and are particularly useful for verifying the straightness of deep holes.
Pin gauges can be made from various materials, including steel, carbide, ceramic, zirconia, and hard metal alloys.
- Steel
- Ceramic (Zirconia)
- Tungsten Carbide
Pin gauges are available both individually and as sets. Sets typically contain a range of sizes with small increments, such as 0.01 mm or 0.001 mm, depending on the precision required. These small increments are crucial, as pin gauges are often used for measuring smaller holes that demand high precision and accuracy. Each pin is marked with its exact size for easy identification.

To use a pin gauge set, begin by inserting the smallest diameter pin gauge into the workpiece hole. Then, gradually insert larger pin gauges in order of size until you find the one that fits snugly in the bore. Do not force the pin gauge into the hole.
The "Go" pin, which represents the lower limit of the bore, should fit smoothly without any force. The "No-Go" pin, representing the upper limit, should not fit, even with slight pressure applied. This method helps ensure that the hole is within the desired tolerance range.
Regular maintenance and calibration are essential to ensure the accuracy of your bore inspections and extend the life of your pin gauge. Neglecting proper care can lead to unreliable measurements and early wear. Below are some key habits to help you maintain your pin gauge:
Start by using your pin gauge correctly. Most pin gauges become inaccurate or damaged due to improper use. A common mistake is applying excessive force when inserting the pin gauge, which can alter its size or damage it. To avoid this, use a pin vise to handle the gauge. This reduces the impact of temperature changes from your hands and helps maintain the tool's precision.
Proper storage is vital for extending the life of your pin gauge. Keep it protected from environmental factors like heat and moisture, which can affect its accuracy over time. We recommend using a dedicated container for your pin gauges. If you have a set, store each pin gauge in a separate small case to prevent contact and potential damage.
Routine maintenance is crucial to ensure your pin gauge stays in good working order. Regularly inspect it for dirt, debris, and oil, as these can cause corrosion and affect performance. Keep the pin gauge clean and free from contaminants to ensure reliable measurements.
Calibration is essential to verify the accuracy of your pin gauge. While most manufacturers recommend calibrating once a year, the frequency should depend on how often the pin gauge is used. For tools with heavy usage, more frequent calibration is necessary to account for wear and tear. Regular calibration ensures the pin gauge remains accurate and reliable throughout its lifespan.
Besides inspection of small holes, pin gauges can be used in many other ways:
- Distance between holes
- Calibrating micrometers
- Width of a groove
- Acceptance judgement
- Dovetail
- Inspection of engine parts
- Overpin diameter of gear
- Deflection of gear
