Tenon(redirected from tenons)
Also found in: Dictionary, Thesaurus, Medical, Acronyms.
(in Russian, ship), a projection on the end or lateral surface of a part, designed to be inserted into a recess or groove of corresponding shape and dimensions in another part. It can be used to effect a permanent or temporary joining of the parts. A tenon may be in one piece with an article, or it may be a separate insert (as a dowel). Joints made by a mortise and tenon are most often used in the manufacture of wooden structural elements (windows, doors, and the like), furniture, crates, and casting patterns. In machine building, end and face journals (pivots) are analogous to tenons; they usually have a cylindrical, conical, or spherical shape.
