Best Screws for Plywood
Plywood splits along its plies when screws wedge them apart. The fix is a thin shank, a sharp point, and the right length: #8 screws at 1-1/4 in for 3/4-in ply covers most furniture and cabinet work. Pilot holes near edges are non-negotiable.
What to Look For
- #8 gauge is the plywood default — #6 for thin stock, #10 for structural.
- Length runs about 2x the top layer — 1-1/4 in for 3/4-in ply into framing.
- Type-17 or sharp points cut fibers instead of wedging plies apart.
- Flat or bugle heads seat flush without tearing the face veneer.
- Pilot holes within 2 in of any edge — plies split fast.

Avoid
- Drywall screws in plywood — brittle, snap under shear, and bury too deep.
- Oversized #10 and larger screws in 1/2-in ply — they jack the plies apart.
- Skipping pilot holes on edges — the number one cause of split plywood.

FAQ
What size screw for 3/4 inch plywood?
#8 x 1-1/4 in is the standard for joining 3/4-in plywood — long enough to bite the second layer fully without poking through. Attaching 3/4-in ply to framing (subfloor, sheathing) steps up to 1-1/2 or 2 in.
Can you use drywall screws in plywood?
They drive and hold in a pinch, but they are the wrong screw: brittle hardened steel snaps under shear loads, and bugle heads can bury past the face veneer. Construction or multipurpose screws cost little more and hold far better.
Coarse or fine thread for plywood?
Coarse thread. Plywood is softwood plies and glue — coarse threads bite aggressively like they do in pine. Fine threads are for hardwoods and steel, and hold weakly in plywood.
