The Tusk Tenon
Another type of mortice and tenon joint used is the Tusk tenon. Arranged to weaken the timbers as little as possible, the tusk tenon is used in floor and roof construction. The tenon – which usually has a thickness of one-sixth the width of the material – is strengthened by projections left on the shoulder. The tenon projects through the timber that it is being jointed to and is secured with a wedge or key. A vertical section and plan are shown below (Fig A), and an isometric view (Fig. B). The tusk tenon, although not used as commonly as it once was (due to the likes of joist hangers), can still be found in floor joists.
