Dear all
What drill bit diameter and bit type would you recommend for 6.7mm timberfix screws. They are 150mm long. I have a 6mm Auger bit which seems ok but wonder if I need a smaller pilot hole
as they are for tying down green oak rafters for the roof of a gazebo project (images attached)
Thanks in advance
Jon
