For example, in M8-1.0*20, the M means the Metric thread designation, the digit 8 refers to the Nominal diameter (in millimeters), 1.0 refers to the pitch, and 20 refers to the length. The ridge surrounding their heads also makes them easy to be identified. Thread pitch. Now that you know how to take the measurement, the next step is to place the ruler down the axis to get the thread count. Coarse threads have a larger threadform relative to screw diameter, whereas fine threads have a smaller threadform relative to screw diameter. SAE J429: The SAE J429 standard is a specification for bolts, screws, and studs that are used in automotive and related industries. If you spot another number next to the class, for instance, 10.8, this number is called the yield strength. The yield strength describes the level of stress it can take before it is bent past the point of no return to its original shape. Here are some of the most common ones.
