When General Tools Oak Flat Head Plugs are glued into screw holes, they create a flush, smooth finish. Flat head plugs are ideal for filling in unsightly screw holes and can be used in a variety of craft, woodworking and furniture projects. The slightly tapered plug body ensures a tight secure fit. Wood grain runs in the direction of the plug width for best match. Paint or stain for a perfect wood-color match or for accentuated contrast.
