If the depth is specified as THRU (for through), the hole passes entirely through the feature. Also illustratedFeb 21, 2012 · If you specify a .250 diameter hole at .500 deep then the hole should be .250 for the entire length of .500. If the tip is included in this then this will not be the case. Adding the DO NOT BREAK THRU note is effective as well. The same goes for tapped holes. The depth should be for the minimum amount of threads. The counterbore symbol is used on a drawing to indicate that a counterbore hole feature is required. A counterbore is a flat-bottomed cylindrical hole that is larger than and coaxial to another cylindrical hole. It is used to provide a flat and recessed mounting surface for mating parts. The hardware most commonly used with a counterbore is a ...First, let’s work on the four length dimensions at the bottom of the left view in Figure 1. For distances like these, we need to use the location dimension per geometric dimensioning and tolerancing standards to define feature locations rather than feature sizes. Defining the longest distance, 1.940 in, and the shortest one, 0.180 in, is easy.In the example below, the part contains two thru holes with countersinks. The diameter of the thru holes is listed as 9 +/- 0.25, and the countersink is called out as a diameter of 19 +/- 0.5 with a conical angle of 90 degrees.
