Pocket hole screw chart
Screw length and thread by material thickness, with the jig and drill-stop setting that has to match it. Set the collar to the material, not to the screw.
| Material thickness | Screw length | Jig and stop setting | Plywood / softwood | Hardwood |
|---|---|---|---|---|
| 1/2" – 5/8" | 1" | 5/8" | coarse | fine |
| 5/8" – 7/8" | 1 1/4" | 7/8" | coarse | fine |
| 7/8" – 1 1/4" | 1 1/2" | 1 1/4" | coarse | fine |
| 1 1/4" – 1 3/4" | 2" | 1 3/4" | coarse | fine |
| 1 3/4" – 2 1/4" | 2 1/2" | 2 1/4" | coarse | fine |
Reading it
- The screw length assumes the hole was drilled where the material thickness puts it. Set the jig collar and the drill stop to the thickness before anything else.
- In a joint between two thicknesses, the hole goes in the thinner piece and the screw is chosen for that thickness.
- Along a long edge joint, holes go about every 8" — and the glue is doing the work, with the screws acting as clamps that stay in.
