I have some new screws for my rear drive shaft and I want to know if I need to put any special coating on the threads
 
Correct term would be bolts. Some medium thread lock would be appropriate. Your choice of brand.
They are in fact, not bolts. We call them that until we have to source them, then they are actually screws. Them grade 8 things with a hex on one end, threads on the other for some to all of the length? Yep, Hex head cap screw. Add a flange, and they become hex head flange screws.

Technically you are probably correct, you get a brownie. However, the issue of what is a screw and what is a bolt is not completely resolved with Machinery's Handbook distinction so we need to consult the Ancient Greeks on this subject.

I think we should make this a thirty, no, thirty two page thread out of this.

I've only ordered and paid for about a million fasteners. That and if McMaster doesn't know what they are, no one does. Call them what you like but just know why. I also call them bolts because it is easier to be all fucked up than try to explain to idiots why they aren't bolts.
