Valve lapping compound for phillips screw heads
Monday, February 08, 2021, 21:22

Put a dab of valve lapping compound in the screw head, it grips that way. You may need to put your vice grips on the screwdriver shaft, or a quarter inch box end wrench on the replaceable tip, to turn the screwdriver. Valve lapping compound trick works with electric screwdrivers too. You won’t want to be without valve lapping compound again. Replaceable tips will shatter occasionally, so use caution.
