joining plywood to hardwood

[Matthew Brown]

i am going to be joining a piece of plywood to a hardwood board  should i be using fine thread screws since i am drilling into hardwood?

[John Schaben]

If I understand correctly the answer would be yes. The threads are going into the hardwood and the pockets are going into the plywood,

[Matthew Brown]

yes that is what i wll be doing.  thanks!! just wanted to make sure!

Hi, Matthew

Yes, the material receiving the screw threads would dictate which screw to use.

Yes but 2 small tips I will offer you; make sure your drill collar is backed off the 3/4" marking just a hair, maybe 1/16". Your plywood is not a true 3/4" as your hardwood is. This will help keep the point your SML-F125 from breaching the surface of the hardwood. Another thing is make sure you have clamp pressure at the screw whenever joining (mostly at the ends) to prevent splitting. I learned that one the hard (expensive) way.
