19.231 (1) The fractional values are the taper standards. (2) Diameters (D1) and (d1) are calculated from the values of (D) and other values of the taper. (values are rounded up to one decimal place). Remarks 1. Tapers are measured using JIS B 3301 ring gauges. At least 75% must be correct. 2. Screws must have metric coarse screw thread as per JIS B 0205, and 3rd grade precision as per JIS B 0209.
