What are dowel pins?

In a manufacturing setting, dowel pins are solid, headless, cylindrical metal rods that have been machined to specific tolerances. These pins are typically used to align, locate, or join component to absorb lateral stress. However, they can also be used as a pivot, shaft, or hinge.

How do I choose a dowel pin?

Diameter: Ideally, the diameter of the dowel should be approximately 1/3 – and never more than 1/2 – of the thickness of the wood being joined. For example, if your product is 1” thick, you should be considering a dowel pin 3/8” in diameter. If your product is 1-1/4” thick, a 7/16” diameter would be more suitable.
