1. Clamp the pieces together and drill the first hole 2/3 the
diameter of the screw. If the material is soft, drill only 2/3
the proper length. If it is hard, drill the entire length.
2. Unclamp the pieces and drill the second hole the same
diameter as the screw shank in the first or top piece of
wood.
3. If flat head screw is used, countersink the hole to make
the screw flush with the surface. Then, simply apply
even pressure when driving the screw. The screw shank
clearance hole in the first piece allows the screw head to
pull the pieces tightly together.
Running nuts and bolts
Variable speed control must be used with caution for driving
nuts and bolts with socket set attachments. The technique
is to start slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by allowing the impacts to
tighten the fastener over a period of time. ie the longer the
impacts, the tighter the fastener.
Note.
Hold the impact driver firmly.
