Anyone have a tip for installing the pins on a gate? All the ones I've seen are one solid piece with shallow threads on one side, maybe 4" or so long and the thumb the gate hangs on on the other side. I've tried using a wrench on the thumb part but it wasn't easy and it chewed up the thumb quite a bit in the process. I will probably get a foot long length of pipe that fits over the thumb and see if that makes a difference, but I'm wondering if you all have any other tips? I drilled the holes 9/16, I think I might need to go up to 5/8 since they are still very hard to put in.
