I am replacing a section of subfloor in my kitchen. I am laying new 5/8 plywood over the diagonal boards, and using 3" stainless steel deck screws that I had left over from building my deck to fasten the subfloor. I am pre-drilling 1/8" pilot holes to make driving the screws in a bit easier.
I am having problems with one joist. Even with pilot holes drilled the full depth of the screw, the screws keep snapping before being fully seated. Drilling the pilot holes into this joist is also a chore, as it is more like drilling into concrete than drilling into wood. The drill bit comes out smoking, and the pilot hole is also smoking. I have never seen this happen before.
I suspect that the joist either has more knots than the other joists, or it has higher density perhaps due to more pitch in the wood than in the other joists. I have tried several spots along the length of this joist, and it seems to be the same everywhere.
Has anyone run into this? What is the solution for dealing with this problem?
Thanks,
