Step-by-step instructions for drawing bolts in autocad. The text from internet.

The procedures are as followed:

A.You should divide the top line into 11 (gives 10 points).

B.Here, you need to make a circle from the rightmost node point to the one just to the left of it.

C.You should draw a line from the center point down to the quadrant point of the circle.

D.You should Use grips to move the end point up to the middle.

E.The last two steps will give you the "Root, which is one-half the distance between two crests" this is needed to make a proper looking tooth. Erase the circle and the vertical line.

F.You should copy the top lines node points to the end of the just created line.

G.You should move the bottom node points to the right one-half the distance between the two node points.

H.Use "Mid between Two Points" on Snaps to do this. Copy the leftmost node point to the left one-node spacing so that you have one more node point on the bottom line.

I.You now have two sets of node points, with the bottom set one-half the distance to the right. Use a pline to go from the upper-right line end and zigzag your way to the left end. You will now have the upper crest and root of the threads.

J.Now erase all the node points on both lines; the only thing left (on the top) is the zigzag pline.

K.Mirror the pline to the bottom line. Notice that the plines' crests touch the same way on the upper and lower lines.

LNow, you should erase the lines, leaving only the two plines. Move the bottom pline to the right one-half the distance between two points. M.Use "Mid between Two Points" to do this. http://www.cadalyst.com/cad/autocad/how-draw-good-looking-bolts-from-trenches-tutorial-11188#sthash.kuEvQ2nK.dpuf

N.Now draw three lines: The first one two crest lines in from the left The second one from root to root just to the right of above The third one from crest to crest just to the right of above

O.Now you can see that they are misshapen. We will now shape them correctly.

P.Delete the rightmost line, leaving one crest line and one root line. Draw a line from the left crest to the third crest over (three crests long) and draw a line from the left root to the next root.

Q.Use the grips to move the endpoint of the first line to the midpoint of the bottom root line.

R.Extend this line to the top crest line. This shows that the crest points need to be moved to the left so that they will be in the middle of the root spacing.

S.Stretch ALL of the crest points from the crest point just to the right of the extended line to the end of the extended line. Hint: T.Stretch all the points, then remove the vertical line so that it stays where it is. Perform the same sequence for the bottom section. U.Erase all the nonessential lines and copy all the vertical lines and fill in the blanks to make it look like bolt threads. It is now necessary to adjust what we have just created.

V. Move the whole assembly from the left crest point to a snap to the right. If you don't, it will be off somewhat and will affect placement. Now draw a vertical pline from below the left bottom lines (dimensionally vertical to the top crest point) up past the top crest point, then to the right 1" and down past the whole assembly. This will help to readjust everything to 1" long.

Copy the crest/root lines to fill in the blanks.

Trim all excess lines to the 1" long reference line. Now you should see properly spaced bolt threads

Once you create one and understand the concept, the process is really quick. You can also use scale and reference to quickly make other sizes (with the same number of threads per inch).
