Dowel Pins

Precisely align machine parts and prevent movement during assembly. These dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. They can also be used as a pivot, shaft, or hinge to join moving components. Since dowel pins can be hard to remove, they are best suited for permanent fixtures that don't require frequent adjustments or disassembly.

Steel

Machinable Carbon Steel—Made of 1215 carbon steel, these pins are the easiest to machine, so you can shape them if they don't quite match your hole dimensions. Stronger than stainless steel but not quite as strong as alloy steel, they won't deform from stress and vibration. Pins perform best in dry environments since moisture will cause them to rust.

Lightweight Aluminum

6061 Aluminum—These pins are one-third the weight of steel and stainless steel. Use them in robotics, automation, and other applications with weight limitations. They're also an alternative to stainless steel for rust resistance but not as strong.

Brass

360 Brass—With a warm, polished look, these pins are typically chosen for their appearance. Suitable for use outdoors, they resist corrosion and won’t become brittle and snap in low temperatures. Brass is softer than other metals, so pins may bend or break under high stress.
