ASME Y14.3-2003:
4.3 Nonsectioned Items in the Cutting Plane
4.3.1 Sectioning Assembled Items. When the cutting
plane lies along the longitudinal axis of items, such as
shafts, bolts, nuts, rods, rivets, keys, pins, screws, ball
or roller bearings, gear teeth, spokes, and the like, these
parts are not sectioned except when internal construction
is shown. See Fig. 47.
4.3.2 Conventional Section Lining of View. Where the
cutting plane is perpendicular, or cuts across the items
in para. 4.3.1, the sectional view is section lined in the
usual manner.
"Wildfires are dangerous, hard to control, and economically catastrophic."
The one and only one that comes to mind is that if it is an industry standard you only have to callout the General info of the screw.....(UNC-30-.25) Can't exactly remember how it goes. (be in civil to long)

The screw thread issue came up in thread1103-159528
ASME Y14.6-2001 para 3.2 addresses the issue of whether to reference the thread standard.
In the US the name and number of the controlling thread standard is frequently omitted from the drawing. Reference is made instead to the designation symbols of the standard, such as series symbols and class symbols. To avoid misunderstanding, it is recommended that the controlling organization and thread standard be specified or otherwise referenced on the drawing.
Section 3-4.3.1 - Where the cutting plane lies along the longitudinal axis of items such as shafts, bolts, nuts, rods, rivets, keys, pins, screws, ball or roller bearings, gear teeth, spokes and the like, these parts are not sectioned except where internal construction must be shown.

Never argue with an idiot. They'll bring you down to their level and beat you with experience every time.
