3/8" Oak Mushroom Button Plug

• Precision fit for 3/8" holes reduces the chance of looseness or later popping out
• Oversized 1/2" mushroom head ensures full coverage of hardware and slight countersinks
• End grain oak absorbs stain to closely match or contrast with surrounding wood
• Quality oak is naturally dense, minimizing wear for a long-lasting finish
• Easy installation with a light tap — the tapered tenon seats firmly with no wobble
• Ideal for cabinetry, furniture, shelving, trim, and floorboard repairs
• Budget-friendly bulk options for contractors, builders, or mass DIYers

Perfect for covering countersunk screws or dowel holes in cabinetry, shelving, staircases, furniture frames, or handrails, these plugs provide a clean, easily stained accent that blends or stands out as desired. They're a top pick for restoration work and new builds where visible fasteners detract from the finished look. For a creative touch, stain them in a contrasting color to highlight joinery as a subtle design detail, or leave natural for a traditional appearance.

• Will these plugs fit metric holes?
  3/8" is equal to 9.53 mm, so these will fit 9.5 mm holes with a similar snugness; check your hole with a gauge to confirm compatibility.
• Can the plugs be sanded flush after installation?
  Yes, once installed, mushroom plugs can be sanded or trimmed for a perfect surface match — but the head is slightly raised by design.
• Are adhesives required for installation?
  No glue is needed for most applications—tapered press-fit secures the plug. Use a dab of wood glue if the hole is slightly oversized or in high-wear areas.
• Is the oak end grain visible after finishing?
  Yes, as with all button plugs, the end grain remains visible and takes stain differently than side grain for a natural accent effect.
• What is the best finish to use—stain, paint, oil?
  Use stain for blending, oil for subtle wood tone, or paint for decorative accent; always test on a spare plug for color match before finishing a project.
• Are larger or custom sizes available?
  Bulk and special order sizes are available through many suppliers if your project requires custom dimensions.
