Wood plugs are small, cylindrical pieces of wood used in various woodworking applications such as filling or concealing holes, gaps, or other imperfections. They help in achieving a finished look in projects such as furniture, decking, and flooring.

These plugs are typically made from the same wood as the surrounding material to achieve a seamless and aesthetically pleasing finish. They also come in various sizes and are also useful for both functional and decorative purposes.

Installation typically involves applying some glue to the plug, inserting it into the hole, and then sanding it flush with the surrounding surface after the glue dries.

Wood Plug Uses

Here are some uses of a wood plug:

• Concealing Screw Holes: Wood plugs can cover up screw or nail holes in furniture and cabinets to create a clean and polished appearance.
• Joinery: In traditional woodworking, wooden pegs or plugs are useful for securing joinery, such as in mortise and tenon joints.
• Decorative Accents: Craftsmen can use plugs as decorative elements in woodworking and furniture design.
• Repair and Restoration: They are suitable for repairing damaged or worn surfaces. They can fill in gaps, cracks, or areas of rot, restoring the integrity of the material. 
• Wooden Boats: In boatbuilding, wooden plugs are used to fill countersunk fastener holes and ensure a watertight seal.

Buying Wood Plugs

Here are some guidelines for buying plugs:

• Determine Requirements: Decide on the size, type, and quantity. Common wood plug sizes include ⅜ inch, ½ inch, or ¾ inch.
• Select Wood Type: They are available in various wood types, such as oak, maple, cherry, and pine. The wood plug should match or complement the workpiece.
• Read Reviews: Do some research first before ordering online or heading to a local store to buy a pack. Make sure that the plugs meet requirements in terms of size, quality, and material.
• Consider Quantity: It is highly recommended that woodworkers purchase wood plugs in large quantities. Extra pieces can come in handy in the future, or in case of mistakes during the procedure.
