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.

Lightweight Corrosion-Resistant Titanium

Grade 2 Titanium—The best of both worlds, these pins are lightweight like aluminum and as corrosion resistant as 316 stainless steel. Because Grade 2 titanium is 99% pure, it's even more corrosion resistant than other common titanium grades, such as Grades 5 and 9. This makes them ideal for use in chemical-processing and water-treatment facilities since they stand up to strong acids and other harsh chemicals.
