Excel Dowel's end grain wood plugs are a trusted fastener-concealment solution used throughout the furniture, cabinet, and stair industries. Available in both flathead and roundhead styles in 3/8" and 1/2" diameters, our end grain plugs are offered in ten hardwood species — birch, beech, poplar, ash, hickory, oak, maple, cherry, mahogany, and walnut — with both standard tapered and straight-sided profiles. End grain plugs are the traditional choice for staircases, furniture, and cabinet construction where a natural, visible wood-grain end face is appropriate and expected. Sold by the thousand with volume pricing, they're an economical and reliable option for production woodworkers and furniture manufacturers who need consistent quality at scale.
