Locating Pin Requirements and Considerations

These are the most important things to consider when choosing dowels for your project.

 

Diameter

The diameter will be the thickness around the dowel. The diameter must match the drilled holes on both sides of the two pieces being joined.

 

Material

Most commonly, you will find dowels in wood, stainless steel, and plastic. Metal dowels are often used to hold metal structures, while wooden dowels are used with wood.

 

Length

In addition to the diameter, you also need to know the length of the dowel. The dowels should fit evenly into the two parts you are connecting. It grips better when the pins are evenly distributed.

 

Hardness

For steel dowel pins, you may notice a reference to the Rockwell hardness scale. This is a way to determine the relative strength of the metal in the pin.

 

If you think you need a solid dowel, be sure to choose a harder Rockwell measure.

 

Remember, the harder the dowel is, the more brittle it will be. This means that you should avoid bumping or dropping the dowels as much as possible.
