Threading handbook?
Threading handbook?
(OP)
Does anyone know of a good reference source for designing threads. I would like detailed information on why different thread forms are used, what the benefits of different types are, and calculations involoved in choosing a proper thread form.
I am currently looking at different variations such as tapered threads, buttress threads, and multi-start thread and I cannot find any information on why people use these and other thread forms. The only thing I can find information about is calculations for standard unified and ACME threads. Any help would be great thanks.

You might want to look at any of the good machinery's handbooks available

I have only encountered buttress threads twice in my life. I still think the OEM used them to "buttress" his spare parts sales.

Anyone know of any in-depth source dealing specifically with threading and thread forms?

RE: Threading handbook?
-What are the advantages of using a tapered thread as opposed to a parrellel thread?
-What are the pros/cons of multi-start threads?
-How do the thread shear areas compare for tapered vs. parrallel, buttress vs. ACME vs. unified.?
-What thread form provides the maximum thread contact area?
-What form is least suceptible to cross-threading?
In general, I am looking for a source of detailed information regarding why different thread forms are used, and how they compare. I have studied the Machinery's Handbook extensively and I would like further detail. Thank-you
RE: Threading handbook?
As I recall the Machinery's handbook is an excellent source for this information however I do believe that their detailed and in depth descriptions have begun to fade over the years. I have the 26th, 23rd and 19th editions and I find that the older the edition the more in depth the information is especially in the machinists and mechanics information. I find the older versions more helpful. There are many websites to be searched if you search for keyword "screw thread applications" you might also try the "Millwrights Handbook"

check out this link for some useful info.
The site belongs to a power screw manufacturer who may be able to give you more details:

You will find limited info on tapered threads. Most of them have evolved over the years to provide sealing (sort of) but they are not the most robust mechanical designs going. The petroleum buttress tapered threads used in well pipe are a different matter; they are very well engineered.
Hope this is useful.
