Suggested Uses

Oak stair plugs have long been used for camouflaging fasteners in staircases, furniture joinery, and custom cabinetry. Carpenters favor them for restoring antique pieces, creating smooth shelves, or finishing handmade furniture with invisible hardware. These plugs are ideal for safely hiding screws in kids’ toys, fixing holes in custom shelving, or reinforcing detailed model builds. For standout results, align the plug’s grain with your project, sand before finishing, and pair with a matching stain or paint for an undetectable repair.
