i just finished putting in a short section of wood fence,4x4 posts and 8ft slats.i used square heads where the 2x4 crossed the 4x4 and phillips head on the slats...i was just using drives that i got out of a fish bowl at my local hardware store.the other stuff was from a big box store.i was stripping out the heads right and left with the driver chattering around.
i'm not a real handy man sort of guy and went back to the big box and asked about that.what i needed was a driver that was the right size! a #2 and by gosh the rest of the fence went up in no time at all.
