Review on Enhance Your Skateboarding Experience with Black Diamond's Old School Plastic Skateboard Rails + Mounting Screws by Daron Ellis

The rails are high quality, but the fittings in the kit are junk. The strip will stick your hole in or out of the board very easily. And if you test one of these out before actually mounting it to the board, you'll find that there's no way to move the screw more than about 1/16-1/8 inch. So basically it only goes up to the first layer. I replaced the strong parts with a couple of screws I had on hand, about 3/8" long, and they worked much better. Also, you couldn't tighten it enough without carving the wood so it wouldn't when doing tricks made a lot of noise.New screws solved this problem.Now it's quiet and well fixed.
