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.

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.
