Kreg Jig Owners Community

I'm starting my first pocket hole project and will be using 3/4" Oak and 3/4" Oak plywood. This may be a silly question but would you recommend the 7 or 8 shank. Of course they would be 11/4" long. Would appreciate your replies.

It silly to ask how are you going to learn I work with alote of oak and I use SF-125 washerhead 1 1/4'' fine threaded scerw's and dont for get to setup your stop collar and use your nickle.

Hi Robert, I use the small shank 1 1/4"  fine thread screw and like David,above,I use the washerhead.  I build out of all types of materials including hard woods like hardrock maple, hickory and the oaks.

The screw is an excelletn fastener with excellent resistance to pull out and plywood ply seperations.

Never have screw breakage and they self tap with ease.  My reason for the small shank is that the larger the screw shank the bigger the chance of seperation of the plys in plywood.

From looking at all the Kreg screw sizes at Amazon, It looks like #7 is for fine screws and for hi-lo screws, while #8 is coarse screws. The shank of a screw means the length of the screw from under the head to the tip. #7 screws have a slightly smaller shank that of #8 screws. This I think is due to the fact that hardwoods are measured differently than softwoods and that hardwoods therefore are smaller in thickness than softwoods (don't quote me on this).

Maybe some of the other members (or KregRep) can better help you out in case I don't know what the heck I'm talking about. :)

In answer to your question then, use #7 fine screws 1¼".

The numbers on a screw like #6, #7, #8 and so on is the diameter of the screw shank.  It can be confusing to most.
