screws for cement board

Turbo Golds or Spaxies for me......... So easy to drive through with an impact driver

Maybe your driver/bit could be the problem. Recently I changed over to use an impact driver,but forgot it one day and asked to use a joiners 18v DeWalt cordless......with the right driver and the right bit it would pull the screws all the way thru the Hardie

i recently changed for cordless makita tools, so impact driver is very good and bit was for this screws. It's just not right for me how this screws perform on hardie
