==Materials used for joining==

* [[Dowel]]s can secure wood joints hold without the use of glue or mechanical fasteners, as in a pinned [[mortise and tenon]].
* [[Glue]] is highly effective for joining timber when both surfaces of the joint are edge grain. A properly glued joint may be as strong or stronger than a single piece of wood.  [[Animal glue]] is soluble in water, producing joints that can be disassembled using [[steam]] to soften the bond.
* Various mechanical [[fastener]]s may be used, the simplest being [[nail (fastener)|nail]]s and [[screw]]s. Glue and fasteners can be used together.

=== Reinforcing joints ===

* [[Dowel joint#Dowel reinforced butt joint|Dowel]]: A small rod is used internal to a joint both to help align and to strengthen the joint. Traditional joints such as butt joints are used with natural timbers as they do not need materials other than the timber itself. Dowel joints are also useful for pegging together weaker, cheaper composite materials such as laminate-faced chipboard, and where limited woodworking tools are available (since only simple drilled holes are needed to take the dowels). The wood species of a dowel may be different from the overall piece to balance strength with cost, and some joinery may leave a dowel end visible as part of the piece's design.

* [[Biscuit joiner|Biscuit joints]]: A small preformed wooden 'biscuit' is inserted in a pre-cut slot to help align an edge or butt joint when gluing. 
* [[Domino joiner]]: A trademarked form of biscuit joiner, using a piece of preformed wood, larger than a traditional biscuit and referred to as a "domino"; has some of the advantages of dowels and of biscuits.<ref>{{cite web| url= https://riverdalejoinery.com/ |title= Bespoke Joinery }} Monday, June 22, 2020</ref>

All reinforcements using wood as the introduced spanning material make use of the item's cellulose fibers to resist breakage. Biscuits or dominos may provide only slight strength improvement while still forming a strong alignment guide for the joint's pieces.<ref>{{cite web|url=https://www.woodworkersjournal.com/biscuits-mortise-tenons/ |title= Loose Tenon Joinery Q&A }} September 29, 2020</ref>
