Kreg P-Map Solid Wood Pocket-Hole Plugs are versatile and high quality plugs that work best with materials 1/2 to 1 1/2 inches thick. These 50-count plugs are made of solid maple wood and can be stained to match your project. The plugs are easy to install by gluing them into place and then trimming or sanding them until they are flush with the surrounding materials. They can be used to decoratively accent or hide pocket holes and are compatible with all Kreg screws except the Kreg Jig HD. Note that they are recommended for indoor use. Before purchasing these plugs please know that they are not compatible with the Kreg Jig HD. At Kreg woodworking is our passion.
