The flexplate screws can be replaced with ARP parts - I don't recall the number offhand, but it's the set for Pontiac that includes six screws, 1/2"-20 x .590"
The screws for the flexplate to the torque converter are, I believe, M10-1.5x15m/m (maybe 20m/m?) but they are also what are called "place screws" - which have a bit of a special head style, and shouldn't be replaced with standard hex heads. I've yet to sort out a part number for those - you may end up having to go to a Jeep or Toyota dealer for those (the AW4 is a Toyota box, and uses a similar torque converter.)

Considering the shear stress on those screws, it's a good idea to replace them if you have the means to do so.
Play nice, now...

I was being sarcastic...
BUT. they're bolts, not screws. no offense, but from a normal standpoint...they're two completely different things. kinda like bolts vs. nuts.
Bolt - any externally-threaded fastener that mates with internal threads in a removable part - commonly known as a nut.
Screw - any externally-threaded fastener that mates with internal threads machined or formed directly into the part.
Stud - any headless externally-threaded fastener with threads on both ends (may or may not be continuous.)
Setscrew - any externally-threaded fastener that mates with internal threads in a part, usually used to hold and adjustment or to fasten a part to a shaft in a removable manner.
So you see, the same fastener can be either a "screw" or a "bolt" - depending on how it mates with the internal thread. A cylinder head 'screw' screws directly into the block - but it can also be used elsewhere with a nut, and become a 'bolt.' The difference is the context of use. Thus, you'll find that most threaded fasteners on a vehicle can be properly called "screws." And yes, a "nut" is any internally-threaded fastener that is separate from a part, whether it's loose, welded to a tab, or some variety of insert (Nutsert, well nut, Rivnut, or whatever.)
I know it's being pedantic, but it's how I think... Very technically, any externally-threaded fastener with a wrenching head is a "screw" - they're called "screw threads," not "bolt threads..."
