The task appears simple, attach a 1/4" thick sheet of hard(ish) plastic to steel warehouse racking using #8 Phillips, wafer head, self drilling screws in some cases 8-10' up on a ladder. Seems easy enough but three of us have tried and all have struggled. Tried different power settings on an impact driver from low to high, including the one for self-drilling screws. The first problem is that the screws grabs the plastic and it rides up the screw. Ok, clamp the plastic in place pita but solves the problem. After that it seems that the slightest deviation from absolutely straight on causes the screw wonder, go off on an angle, the bit slips out, and you end up driving the bit into the plastic leaving a divot. Mr. George...
Tried a small pilot hole and that helps somewhat but is time consuming and driving the screw through the plastic can send it a bit off course, so it's not guaranteed to hit the pilot hole. I had Wera's Impaktor bit holder and it worked pretty well for driving wafer head screws but at least the one I had seemed like the bit holding part wasn't centered on the magnetic outer ring and the ring just chewed up screw heads and we're using black painted screws... I suppose a paint marker could cover that up but one more step.
Any suggestion, besides hiring more skilled workers.
