# 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](/machine-workshop/resources/video-library/build-projects/build-a-box.md). 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](/machine-workshop/making/step-by-step/joining/dovetail-joint.md), it doesn’t resist to pushing and pulling forces as well as a dovetail joint does. To resist forces a finger joint requires [gluing](/machine-workshop/making/step-by-step/04-glueing.md), and given its large cross grain gluing surface areas it can be strong a strong joint once glued.

## How do I make it?

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](/machine-workshop/spaces/machine-workshop/equipment/untitled/router-table.md) 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.
