For example, “1/2–14 NPT” identifies a pipe thread with a nominal inside diameter of 1/2 inch and 14 threads to the inch, made according to. The external thread allowance may thus be used to accommodate the coating thickness on coated parts, provided that the maximum coating thickness is no more than one-fourth of the allowance.

Note 3: The minimum diameters of Class 1B, 2B and 3B threads, whether or not plated or coated, are basic and give no allowance or clearance for assembly at. The mechanical advantage of a screw thread depends on its lead, which is the linear distance the screw travels in one revolution.

In most applications, the lead of a screw thread is chosen so that friction is sufficient to prevent linear motion being converted to rotary, that is so the screw does not slip even when linear force is applied, as long as no external rotational force is present.

ISO metric internal threads are identified by the use of capital letters for the tolerance position. ISO metric external threads are identified by the use of lower case letters for the tolerance position. As an example: M6 x – 4g6g indicates a metric thread form “M”, “6” mm nominal diameter.
