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.

The widest grip gives you the most leverage. These pins are the easiest to grab with gloved or slippery hands but take up the most space when installed. They have two retaining balls that lock the pin in place until you push the button to insert and remove.

Remove pins even when you only have access to one end or they sit flush with the surface of your part. With one internally threaded end, they are easier to remove than most dowel pins. Thread a screw into the pin and then pull with the removal tool (sold separately). You can also pull the screw with pliers, but there’s more risk of damaging the hole.

A second retaining ball gives these pins more holding power than standard ring-grip pins. They resist loosening from vibration but require a strong tug to pull them out. Good for tight spaces, the split ring folds down out of the way when installed, and you can grab it with one finger to remove. Attach a lanyard to keep pins from getting lost, or add tags to identify components.
