How Kreg Joints™ Work
Kreg Joinery™ is an incredibly fast, strong, and simple way of joining wood. It essentially involves drilling a hole at an angle into one workpiece, and then joining it to a second workpiece with self-tapping screws. While it may seem simple, the technique is revolutionary because when you’re done assembling, there’s no need to leave your joint clamped up for hours, glue is completely optional, and – since you’re only machining one workpiece – there are no frustrating alignment problems to deal with. Kreg Joints™ are so simple they can be built in just a few easy steps!
The first step is to drill pocket-holes in your first workpiece. A pocket-hole is created with a specialized drill bit that features a stepped pilot tip. The step of the bit creates the flat-bottom ‘pocket,’ which seats the screw, while the tip creates the guide-hole for the screw to follow as it’s driven into the second workpiece. The flat step created by the bit ensures that the screw head seats firmly in the bottom of the hole, resulting in an incredibly strong and tight joint.
Each Kreg Jig® features lifetime-guaranteed hardened-steel drill guides that guide your bit at a precise angle as you drill the pocket hole. The angle of the pocket hole is optimized for strength and flexibility across a wide range of material thicknesses, and ensures that your screw always exits at the center of the workpiece.
To drill the pocket hole, simply place the workpiece in the Kreg Jig®, clamp it down using the built-in toggle clamp, adjust your depth, and drill the hole! For panel joints, put one hole about every 6-8 inches. For rail/stile joints, put two holes evenly across the joint, depending on the width of the workpiece. The Kreg Jig® features three uniquely spaced holes so you can find just the right spacing for your workpiece.
With the pocket hole drilled, the second step is to connect your workpieces together with specialized Kreg self-tapping screws. Clamping the joint ahead of time ensures that it will stay in place as you drive the screws. Again, there is no need to drill a pilot hole into the second workpiece at all. Simply clamp the two pieces together using either the Kreg Face Clamp™ or Right Angle Clamp, and drive the screws to secure the joint. No complicated alignment and no waiting for the glue to dry!
Kreg Screws include many features which make them
uniquely suited for use with Kreg Joints™:
That’s it — you’re done! In just a minute or so, you’ve created an incredibly strong joint that requires minimal (if any) sanding and doesn’t need to be clamped while waiting for the glue to dry! Once you’ve tightened the screw, you’re ready to move on to the next joint or even start finishing!
