The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than 1 / 4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.
M-thread The designation used for international ISO metric screw threads. BSP British Standard Pipe, a type of threads originating from Britain. UNEF A Unified Thread Standard originating from the USA, where the EF designation indicates an "Extra Fine" thread pitch.

U.S. Standard threads became the National series (e.g., NC, NF, NEF), which became the Unified National series (e.g., UNC, UNF, UNEF); see Unified Thread Standard. As for U.S. Steel, it was once the largest steel company on earth, often an approved supplier, and not infrequently a sole source; hence its mention on drawings. UTS
The major minus pitch technique also works for inch-based threads, but you must first calculate the pitch by converting the fraction of threads-per-inch (TPI) into a decimal. For example, a screw with a pitch of 1/20 in (20 threads per inch) has a pitch of 0.050 in and a 1 ⁄ 13 in pitch (13 threads per inch) has a pitch of 0.077 in.
The most widely used thread standard internationally. Specified by the International Organization for Standardization (ISO). [10] Threads are defined by their nominal diameter and pitch (distance between threads) in millimeters. For example, an M10x1.5 thread has a nominal diameter of 10 mm and a pitch of 1.5 mm. Unified Thread Standard (UTS)
Pierceable gas cylinder Gas cylinder with Lindal B188 valve.. EN 417 is a European Standard concerning non-refillable metallic cartridges for liquefied petroleum gases.The standard specifies material, construction, inspection and marking requirements for cartridges with or without a valve, for use with portable appliances which comply with the requirements of EN 521.
