| Vernier Calliper Gauge | ![]() | Use for taking internal, external, and depth measurements, typically up to 20 cm to a high precision. | No |
| Dial Gauge | ![]() | Used to measure fluctuations from a defined point. Typically used on rotating objects, for example, brake discs or wheels, to test for lateral run-out. | No |
| Feeler Gauges | ![]() | Used to measure the gap between two parts. Various thickness blades provide standard gap sizes. The blade thickness is stamped on each one. | No |
| Brake Disc Calliper | ![]() | Specifically used to measure the thickness of brake discs to an accurate level. This is needed because brake discs wear with use and need replacing if they get too thin. | Yes |
| Tyre Tread Depth Gauge | ![]() | Used to check the amount of tread left on a tyre. The point is placed in the groove of the tyre and the flat plat is pushed against the tread. A reading showing the difference between the two positions indicates the tread depth. | Yes |
| Tyre Pressure Gauge | ![]() | A simple device used to indicate tyre pressure. The gauge is pushed onto the tyre valve and the end extends an amount proportionate to the pressure. A reading can be taken from the extended shaft. | Yes |
