Then I'd suggest pilot holes with a 1/8 drill bit. 12 volts is typically pretty weak for driving a deck screw. Good luck with the endeavor.Your drill sounds like one my SIL would use who re-models homes. He's too far away to go borrow one of his. Mine--12V re-charge battery, not one for just hanging pictures etc. but it is not heavy duty or professional grade. It has been good for anything I have done with it. I'm re-modeling my house and it has worked for lots of different tasks. I can't justify buying an expensive drill I will use for one project. May just have to fight with these deck screws to get it done.
