What size drill bit to use for predrilling?
I am connecting two 2 x 4s together withe drywall screws.
I am using 2.5" screws.
I will be going through the entire 1.5" of the first 2x4 and 1" of the second 2x4.
My question is
a) what size diamteter drill bit should i use to predrill
b) how far deep should I predrill?
Any general rules, tips, tricks that you go for when predrilling?
thanks
if they are self tapping screws you shouldn't have to predrill. it doesnt matter the length of the screw it is the diamater. Usually you got about 1/16 less than the diameter of the screw for small screws
