The workpiece is then butted against the adjoining piece and joined using special pan-head self-tapping screws.
Kreg produces a number of kits and jigs to suit any budget or shop setup, ranging from a small pocket-sized mini to more elaborate kits with built-in toggle clamps and dust collection.A crucial component of any pocket screw kit is the step drill bit. This bit drills a square-bottomed hole for the screw head to bear against and a shank hole for the screw body to pass through.Many of the tools you already have in your shop will also be pressed into service, such as a drill. If you are drilling a lot of pocket holes, you might consider dusting off the old corded drill since battery life won’t be an issue. A cordless drill with a clutch is ideal for screw driving and will help avoid driving the screws too far. Just as with any other type of joinery, pocket screws work best with clean, square, tearout-free project parts.The screws themselves are of the pan head self-tapping variety.

Generally-speaking, I use fine threads for hardwoods and coarse threads for softwoods, plywood, and composites. These specialized clamps work very much like vise grips, but the wide faces help keep the surfaces flush as you drive the screws home. Many times, I will employ an additional clamp (F-style or parallel) across the joint just to help ensure everything is held as tightly as possible.Once the screws are set, you can remove the clamps and move on to the next step, even if glue is involved. I use them not only to join together the solid wood face frames, but also to attach solid wood reinforcing edging for plywood shelves and the plywood boxes as well. Pocket screws also work very well for attaching table tops, flat mitred items like picture frames, legs on occasional tables, and repairing broken pieces of furniture.
They are made out of many common wood species and you can find one to match or you can use a contrasting species to make a statement.Remember also that the screw and wood are dissimilar materials.

While they hold well for static loads, when you use them in projects that deal with a lot of shifting loads and racking forces, specifically chairs, you definitely want to lean toward more traditional, beefier joinery methods.Pocket screw joinery is fast and strong. While I don’t use them on every project that leaves my shop, I do find them incredibly useful and my Kreg Jig was a solid investment.ExamplesHere are some great examples of projects made using pocket screws from the Wood Whisperer community!
