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.
The knot was popularized as the uni knot by Vic Dunaway, an editor at the Miami Herald, in a 1970 fishing book. [3] [4] Currently, in American English the knot is known as the uni knot referring to its ability to work with mono-filament or fluorocarbon fishing lines. However, in British English it is commonly known as the Grinner knot. [5]
A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ...
The original trapezoidal thread form, and still probably the one most commonly encountered worldwide, with a 29° thread angle, is the Acme thread form (/ ˈ æ k m iː / AK-mee). The Acme thread was developed in 1894 as a profile well suited to power screws that has various advantages over the square thread , [ note 1 ] which had been the form ...

The timber hitch and half hitch Killick hitch perhaps best demonstrates the directional force effect as he shows it as the first knot in the chapter right after the previous discussion as context . [5] After showing the Half-Hitch preceding as only conversion for the direction adds: "The knot appears to be universal and invariable"! [5]
The knot count would be reported and used in the sailing master's dead reckoning and navigation. This method gives a value for the knot of 20 + 1 ⁄ 4 inches per second or 1.85166 kilometres per hour. The difference from the modern definition is less than 0.02%. Derivation of knots spacing:
