Standard dowel pins are cylinder-shaped rods that insert into holes and press-fit into place. They are versatile with many uses, such as aligning components and joining building materials.

Press-fit dowel pins are similar to standard dowel pins but are slightly oversized to create a tighter fit. They are used with a hole that is slightly smaller than the pin and installed using an arbor press or similar device.

Slip-fit dowel pins are slightly undersized compared to standard dowel pins, allowing them to slide freely and help locate the pin in the hole. They are commonly used for rough alignment when assembling parts.

Pull-out dowel pins insert into holes, align components, and hold them together. They feature tapered ends that allow for easy installation and internal threading that connects to a slide hammer for removal. They are commonly used with holes that are only accessible from one side or when a pin must be removable.

Flat-vent pull-out dowel pins function just like standard pull-out dowel pins with the addition of a small flat face along their length that allows fluid and gases to pass freely. This allows them to be installed in applications where pressure equalization or fluid drainage is critical. They also feature an internally-threaded section to allow for extraction in blind-hole applications.

Fluted dowel pins feature grooves along their length that provide space for adhesive and allow the pin to deform for a tighter fit.
