I remember talking about this before, but I haven't heard if anybody has done a build with the drive screws yet.

Just checking in to see if anybody has done one yet. I am going to get another kit and would be interested to know if these are going to work or not, but I am not ready to be the "guinea pig".

Winn bought a box and sent me a few to try, but I have not tried them yet.
I'm concentrating on finishing up the 2 Mausers I've been building.
AK builds are on hold until September 14th.

I don't know if Winn has tried them yet.

worked great.Shorten them up and hamered them in.Just used them on the front turion.Went out and shot 100 rounds still tight.look good

Built an AMD65 with them, haven't shoot it as yet. Used them on both ends, long ones on the rear.

Sweet, I will have to try this now. Maybe on one of the TAPCO $59 dollar AMD-65's.

Thanks

What makes these screws different from regular screws? Do you still need to tap?

drive screws have a fast spiral, instead of threads. they are used for putting nameplates on machinery, and are designed to be driven into drilled holes of a specific diameter. the flutes cut into a mild steel sidewall, but will not cut into the harder steel of a forged steel trunnion. as an experienced fabricator, and auditor of industrial fabrication, i would NOT use these.

sorry guys.

I have never used these except for what they were designed to be used for. Nameplates on equipment and machinery, namely milling machines, and such, and electric motors and gearboxes.... all cast iron. The cast is soft enough to let the threads cut into the drilled hole, but if using them in something harder, the threads, I believe, would just sort of mash in and pien over, and you would end up with just a tight fitting pin. Just what my theory is, though, and if you guys try it out, I'd love to hear your side of the story...:thumbup1:

I also tryed them out on my center support.Work great until i hand to take them out to shorten the center support.Tryed turning them counter clockwise would not turn.Ended cuting the heads off.They are tuff.The key is to use the right pilothole.Use a brass hammer.

I understood that these are NOT the same as the drive screws that are used to fasten name plates to motors etc. I understand that these are harder than those lightweight ones. I would like some commentary from some of the guys who have actually used them as to their hardness and suitability. Anybody else?
