Use a ‘Bit & Screw Holder’ when using 3-1/2 inch screws. This handy little device comes in most drill sets, and really helps to set up and screw the 3-1/2 inch screws into place. It totally prevents you from dropping the screw and having to hold on to it at point of entry. If you have one, we highly recommend using it, and if you don’t, you might want to consider purchasing one.
