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 ...
For both of these rules of thumb (85%/90% and major minus pitch), the tap drill size yielded is not necessarily the only possible one, but it is a good one for general use. The 85% and 90% rules works best in the range of 1 ⁄ 4 –1 in (6.4–25.4 mm), the sizes most important on many shop floors. Some sizes outside that range have different ...
where is the tap drill size, is the major diameter of the tap (e.g., 10 mm for a M10×1.5 tap), and pitch is the pitch of the thread (1.5 mm in the case of a standard M10 tap) and so the correct drill size is 8.5 mm. This works for both fine and coarse pitches, and also produces an approximate 75% thread.
It is officially titled: Standard Specification for Quenched and Tempered Alloy Steel Bolts, Studs, and Other Externally Threaded Fasteners. [ 1 ] This is a standard set by the standards organization ASTM International , a voluntary standards development organizations that sets technical standards for materials, products, systems, and services.

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)

The A36 (UNS K02600) standard was established by the ASTM International. The standard was published in 1960 and has been updated several times since. [ 2 ] Prior to 1960, the dominant standards for structural steel in North America were A7 (until 1967 [ 3 ] ) and A9 (for buildings, until 1940 [ 4 ] ). [ 5 ]
