Hi, I know some people are tired of reading about AR and AK rifles, but I'm gutting out a Romanian kit that I'm using to build a rifle with and wanted to offer some fasteners to others who are doing the same thing I am. I ordered some U drive screws but they come in quantities of 100 only, so if anyone in the bay area needs some screws for their AK build, I can give you some. There's no need for all of us to order 200 screws each and use only 10 of them.

I heard about this at gunco and ar-15.com. They look just like rivets, the thing is you don't have to take out the barrel to properly put them in, which is good for those of us who don't have a lot of equipment.

And you dont "screw" them in, you use a hammer or press them in, the shaft on them is fluted so then twist and dig in as they are being driven into the holes you drill.

The U-drive "screws" are really splined rivets with spiral splines that bite into the surrounding metal so they don't fall out. Unlike traditional screws, you don't have to tap threads into the hole to use u-drive fasteners. The way I'm going to do this is just drive out the old rivets in the trunnions, then hammer or press in the u-drive screws with the trunnion in the receiver. Then I won't have to remove and reinstall the barrel or have to squish a rivet into the trunnion with a special tool I don't have. I haven't decided about the rear trunnion that mounts the shoulder stock, but I think I'll also use u-drive screws with that one also. Anyway, I ordered #10 and #8 fasteners, and can spare a few to anyone in the bay area who's building an AK. I'm in Fremont, but one can buy the fasteners online at fastenal's web site.
