Is there any practical difference?
What I’ve seen is that there’s additional/ different threads up towards the head, I guess to get more bite in the softer composite material. I’d suspect that for some brands who sell both (GRK,deck mate), a #8,9,or 10 will be the same, screw to screw, the shear strength would be the same, pullout maybe superior for the composite type.
I’d think that when doing trim, be it with composite or wood, the composite type screws would pull the trim board tighter to the underlying structure. But is that a bad thing if my construction is fully wood?
For most stuff where Im not using nails, Spax is my go to. I do have some GRK structural screws. But for (wood) trim boards, I’m looking at other screws. Any reason to select/avoid the composite type?
