Actually don't like using Torx bits because they are hard to center deep in the channel. I had misplaced these forcing me to order replacements. My plan is to insert Torx bits before screwing in and using jb weld to secure the bit to the screw, giving me a hex head. Can't find this special screw with a hex head. This screw is called AGC-408 by craftsman.
After replacing the piston, cylinder sleeve and O-rings, the old compressor works like a champ. The hardest part was getting the nut loose holding the piston & bearing in place. Two socket wrenches and a big hammer was able to break the nut loose and get it off.
