# Finger joint ## What is a Finger joint? A finger joint, also known as a box joint, is a decorative joint commonly used for [box making](https://ms-kb.msd.unimelb.edu.au/machine-workshop/resources/video-library/build-projects/build-a-box). It is made up of 2 pieces with squared pins along their edges, allowing them to interlock with one another. Whilst visually it is similar to a [dovetail joint](https://ms-kb.msd.unimelb.edu.au/machine-workshop/making/step-by-step/joining/dovetail-joint), it doesn’t resist to pushing and pulling forces as well as a dovetail joint does. To resist forces a finger joint requires [gluing](https://ms-kb.msd.unimelb.edu.au/machine-workshop/making/step-by-step/04-glueing), and given its large cross grain gluing surface areas it can be strong a strong joint once glued. ![Figure 1.

The process to create a finger joint will vary from project to project. To make this this joint in the easiest way possible, you can use the [router table](https://ms-kb.msd.unimelb.edu.au/machine-workshop/machinery-materials/equipment/untitled/router-table) and Incra positioner available in the **MSD Machine Workshop**. For more information, below is a video demonstrating making a finger joint using a router table and Incra positioner. **Note:** Unfortunately it does not take only 3 minutes to create, like in the video. {% embed url="" %}
