Hi, all:
does anybody know any good reference book where I can find thread as
well as helix angles for different types of screws?
Thank you,

The helix angle is easy. If you know the diameter and the number of threads
per inch you can calculate the helix angle with simple geometry.
The reciprocal of the threads-per-inch is the lead. The pitch diameter multiplied by pi is the circumference of one thread. Unwind one turn of thread and you have a triangle with the adjacent side equal to the circumference and the opposite side equal to the lead of the screw. You do the math.

Google gets over 4 million hits on "thread form" and the first few have
the sort of thing you are asking.
