sectioning
can anyone give me a quick ref to the standard for not sectioning shafts and screws on a drawing
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.

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 re
namdac,
you are correct, but the thread is about sectioning.

the screw thread issue came up in
multi and secional view drawings asme/ansi y14.3
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.
