I have has good luck using clutch head screwdriver bits that go in the end of the magnetic screwdriver. The nice thing you can do with these is insert the bit into the screw head and tap it (with moderate force) with a hammer. This sets the bit in the screw head tight and all of my clutch head screws (that I could get to ) came out with no problems on my 48. You could use a screwdriver but the handle tends to dampen the force of the hammer and doesn't set into the screw head as well.
