Metric threaded rods are marked on the end with a color code to define the ISO strength class. The color codes are: [9] Unmarked — 4.6 class (tensile strength = 400 N/mm 2, yield strength 240 N/mm 2) Yellow — 8.8 class (800 N/mm 2, 640 N/mm 2) Green — A2 stainless steel (304) Red — A4 stainless steel (316) White — 10.9 class (1000 N ...

[1]: 71–72 [2]A cue stick (or simply cue, more specifically billiards cue, pool cue, or snooker cue) is an item of sporting equipment essential to the games of pool, snooker and carom billiards.
A minimum root-crest clearance of 0.01 in (0.25 mm) (diametral) between opposing threads with 10 tpi (threads-per-inch) or fewer, and 0.005 in (0.13 mm) for finer pitches. (This is also true for the minor diameters of the Centralizing Acme thread, though not its major diameters, where the allowance is made less than the PD allowance.)
The metric rod has major numbered graduations in meters and tenths of meters (e.g. 18 is 1.8 m - there is a tiny decimal point between the numbers). Between the major marks are either a pattern of squares and spaces in different colours or an E shape (or its mirror image) with horizontal components and spaces between of equal size.

The article contains a list of drill sizes to be used with particular taps. It would be appropriate and useful to also include a chart showing the nominal rod sizes to be used with particular dies. (E.g., a 0.125" or 1/8" rod for use with a 5-40 die; etc.) — Preceding unsigned comment added by 70.89.176.249 21:56, 28 January 2019 (UTC)
A standard metric (concrete) block is 190 mm wide, 390 mm long, and 190 mm high, which allows for 10 mm mortar joints in between bricks, giving a standard unit size of 200 mm square by 400 mm long. [3] A standard metric brick is 90 by 57 by 190 mm; with 10 mm of mortar, that produces a standard unit of 100 mm x 200 mm. [3]
A rod is the same length as a perch or a pole. [24] In Old English, the term lug is also used. The length is equal to the standardized length of the ox goad used for teams of eight oxen by medieval English ploughmen. [25] The lengths of the perch (one rod unit) and chain (four rods) were standardized in 1607 by Edmund Gunter.
