Do GM cars use metric or standard?
5 Answers. To directly answer your question: GM cars are primarily (if not entirely) Metric these days (probably since the mid-to-late 90’s).

Do British cars use metric or imperial?
Britain is officially metric, in line with the rest of Europe. However, imperial measures are still in use, especially for road distances, which are measured in miles. Imperial pints and gallons are 20 per cent larger than US measures.

With only a few exceptions, all vehicles now use the metric system for hardware.
When did American car manufacturers switch to metric?
What sockets do American cars use?
For this, you’d get a 1/3inch wrench or socket. Typically, SAE sockets and wrenches are used on American-made cars, as mentioned previously, however, when it comes to working on imported cars (assuming you’re in the USA) you’ll most likely be looking for metric units of measurement.
How do you tell if a bolt is metric or SAE?
Metric and SAE fasteners are measured differently and with different vocabulary. SAE nuts, bolts and screws are measured by their thread count, or TPI (threads per inch) and their length. Metric fasteners are measured by length and pitch, or the distance between threads.

How do you find the gauge of a metric screw?
Metric Screw Sizes Explained. The gauge (imperial) is half the imperial diameter (in 16th of an inch) of the screw head, roughly. The precise relationship of imperial screw head sizes and the gauge can be calculated. The formula is as follows: (Head diameter in sixteenths is an inch X 2 ) – 2 = Gauge. E.g.
