Made from quality hardwoods. When fully seated, the domed head, button or mushroom protrudes above the surface of the wood and over the edge of the screw hole adding a more decorative look. The button head screw cap is tapered to ensure a tight and secure fit. The wood grain runs in the direction of the width of the plug for a better blend of wood grain. Sanded and ready to accept paint or stain. Species: walnut. Hole size: 1/2 inch. Quantity: 12 pieces
