To finish off a pocket hole joint you will need to insert a plug into the open hole. The plug covers the visible screw and hole making the joint unnoticeable. Once in place the solid wooden plug can be sanded, planed, stained or painted to match the rest of the workpiece, to make the joint completely invisible. This pack contains 100 premium quality solid pine pocket hole plugs, each one sawn and finished to exact dimensions. The plugs are 9.5mm in diameter and can be used on wood thickness between 12mm and 38mm. Every plug is kiln dried to prevent the plug from shrinking in the joint. ©
