Pocket hole screw size for 1/2" material
Half-inch stock is near the thin end of the pocket-hole range — thin enough that screw length and jig setup really matter, because a screw that's a hair too long will blow through the face.
Here's the pocket-hole screw length for 1/2" material, and which thread to use for your wood.

What 1/2" stock is for
You'll join 1/2" material on small and jewelry boxes, drawer boxes, thin plywood panels and dividers, lightweight face frames and picture frames, and general thin-stock craft work.
At 1/2" the screw length is unforgiving, so set your jig for thin stock and test on an offcut before you commit to the real piece.
Using a Kreg jig?
Set the drill guide to your material thickness. For the exact depth mark on your specific jig, check Kreg’s official screw-selector chart — the settings vary by jig model.
Common questions
What length pocket hole screw for 1/2" material?
For 1/2" (12 mm) stock, use a ¾" (19 mm) pocket screw. Pocket-hole screw length is set by the thickness of the piece the pockets are drilled in.
Coarse or fine thread for 1/2" material?
Match the thread to the material: coarse-thread pocket screws for softwood and plywood, fine-thread for hardwood and MDF.
Do pocket hole screws need a pilot hole in 1/2" stock?
No — pocket screws are self-tapping, and the jig's stepped bit drills the pilot in the first board. Just set the jig and the drill-guide collar for 1/2" material.
