Dowels, biscuits and domino’s are wooden connectors that help align and reinforce wood joints. They are often used to join weaker materials such as laminated particle board, as opposed to traditional joints that can be carved out of solid timber without additional wood pieces.

Dowels are short wooden rods that can be inserted into a drill hole on both sides of the wood to be connected. Biscuits are flat ‘biscuit’ shaped wooden pieces that are used to help align an edge or butt joint when gluing. A domino joint is larger than a biscuit and has some of the advantages of dowels and some of biscuits.

The most straight forward wood connectors are made from beech, birch, mahogany or oak, but they are available in any imaginable wood type. There are also special types of dowels and biscuits on the market that are metal or plastic.
