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.

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.

Where these numbers come from
Pocket-hole screw length is set by the actual thickness of the board the pockets are drilled in — standard pocket-hole practice, cross-referenced against Kreg’s published guidance. Thread follows the receiving material: coarse for softwood and plywood, fine for hardwood and MDF. The exact drill-guide depth setting is proprietary to your jig, so for that we defer to Kreg’s official screw-selector chart rather than reproduce it here.
These are general guidance sizes cross-referenced from common woodworking sources. For structural, load-bearing, or manufacturer-specific work, follow the fastener manufacturer’s or an engineer’s specifications.
