All bolts have torque values and some bolts are single use (torque + angle = stretched permanently). There is no such thing as good n’ tight : 1/4″, 3/8″, 1/2″ metric torque wrenches – Make sure it has a metric scale, BMW service documentation is always metric.
As with all wrenches, you have the choice between U.S., also known as standard, or metric sizes. American cars are assembled with nuts and bolts that use standard measurements while foreign cars almost exclusively use metric measurements.

Does SAE mean standard?
SAE, or standard, is used on most domestic models, while metric applies to foreign or non-domestic vehicles.

Is metric more accurate?
Metric is simply a better system of units than imperial
The metric system is a consistent and coherent system of units. In other words, it fits together very well and calculations are easy because it is decimal. This is a big advantage for use in the home, education, industry and science.
