Vented Pull-Out Dowel Pins

Insert and remove from blind holes with less effort than pins that aren't vented. The vent relieves trapped air, so pressure doesn't create resistance as you install the pin. Because they have a tapped end, you can thread in a screw and pull the pin out with a removal tool (sold separately). You can also pull using pliers, but there’s more risk of damaging the hole.

Spiral Shaft

For a more secure hold under vibration than flat-shaft pins, the spiral makes 360° contact with the hole.

High-Strength Alloy Steel—Our strongest, most wear-resistant pins, these won't bend or break from vibration. Use them for high-stress applications, such as mounting and aligning hydraulic cylinders and injection molds. They perform best in dry environments since moisture will cause them to rust.

Pin Removal Tools

Puller Handle—A complete removal tool requires a puller handle and a tip that fits your pin diameter. To use, thread a tip into the puller handle and then place the tip over the screw in your pin. Slide the weight along the handle to pull the pin out.
