In the absence of a standard note on the drawing or a backup design standard that is cited either in a drawing note (preferably) or buried in the purchase contract somewhere the following would be a good threaded hole callout to cover female thread linear features: M4x0.7H Depth 8.00 min, 12.00 max hole depth, CSK 5.00/5.50x40/50 It has a diameter of 0.112in (0.28cm). Are the male and female referring to the threads on the adapter? Is it the true position of the Pitch Diam? To begin answering Tims question, we will refer to our Geometric Dimensioning and Tolerancing standard. The Controlled Radius symbol is a variation of the Radius, and is used when the surface of the contour is required to be a "fair" curve. The basic callout system is meant for machine screws. We often observe one measurement error using a best fit gauge pin to locate threaded holes when this procedure is not called out on the drawing. Consider a hole defined with a positional tolerance of 1 mm. You can think of them as an anchor for the entire part; where the other features are referenced from. Create the hole note callout by adding the hole feature parameters to the dimension. The cut feature must contain a circular sketch: You can add tolerances and precision to hole callouts: You can add hole callouts in standard drawing views and in section views. Perpendicularity is a fairly common symbol that requires the referenced surface or line to be perpendicular or 90 from a datum surface or line Runout is how much one given reference feature or features vary with respect to another datum when the part is rotated 360 around the datum axis.

Webthreads, and the smaller lead angle allows for finer tension adjustment. The conical taper symbol is placed with a dimension value to indicate that the value is controlled as a standard taper. We can then use basic dimensions referencing the hole locations to datum planes B and C to define the holes true position. Unified threads (in inches) express diameter as a fixed number #0 through #10, like example A listed above. You can also place a note with the control frame, under symbols there is a check box to place a note Moven' on, very interesting though. The exception is flathead screws, which are measured from the top of the head.
