Keep the Joint Flat
When assembling parts using pocket holes, it s common for one part to slide past the other, causing an offset in the joint. To prevent this, clamp the parts to a flat surface for assembly, using a jig like we show at right. Clamp it to your bench, and you'll have both hands free for assembly.
Pocket-hole screws arc pan-headed and self-piloting. You will not need to pre-drill the adjoining piece. A square drive makes it easier to keep the driver tip engaged (sec Sources, below). The fine-thread version works best in solid wood, while coarser threads work better in man-made materials.
