Hi I'm new to this form and have a question about using the Kreg system and the type of screw to use.
The material is 1.2"
Hard Maple, Butch Block Counter Top.
The chart tells me to use a 2.5" screw
and a fine thread for the Maple
I am not able to fine that type of Kreg Screw.... So will a course thread work?
Thanks for your help....
Course will work in hardwood but fine will hold better.The reverse isn't as good, i.e. fine screws in man-made wood. You can get the different types of Kreg screws at Amazon and other online sellers.
I would not recommend using coarse threaded screws in hard wood material as this greatly increases your chances of splitting. For this application I would set both the jig and the depth collar to the 1 1/8" setting and use a 1 1/2" fine thread screw. This will give you almost an inch of screw into your receiving piece. If you have any additional questions please let us know.
