Dowel Pins

Use these metal dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts.

Pull-Out Dowel Pins

To remove these pins, thread a screw or tool into the tapped hole, then pull them out.

Flat-Vent Pull-Out Dowel Pins

The flat side of these pins relieves trapped air, making them easier to insert in and remove from blind holes. To remove, thread a screw or tool into the tapped hole, then pull the pin out.

Ejector Pins

Push parts out of molds with these hardened pins. Also known as knockout and forged pins.

Slotted Spring Pins

Also known as roll, tension, split, and expansion pins, these pins have a slot along one side that you squeeze closed to install them into unthreaded holes.

Coiled Spring Pins

These spiral pins remain flexible after installation, so they absorb shock and vibration better than slotted spring pins. They work well in holes that are out of round.

Taper Pins

To remove these pins, hit the small end with a punch to drive the pin out.

Threaded Taper Pins

Threads on these pins stick out for easy removal from blind holes. Tighten the hex nut to draw the pin out.

Metric Partially Threaded Studs

Screw the threaded end of these metric studs into a tapped hole and use the unthreaded end as a pivot point, hinge, shaft, or locator pin.

Headless Alloy Steel Precision Shoulder Screws

Without a head to get in the way, these screws fit in tight spaces where standard shoulder screws cannot. Either thread them in a countersunk hole for a flush mount, or install them with the shoulder sticking out to use them as pins or dowels for aligning and locating components.

Dowel Pin Assortments

Dowel pins are commonly used as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. They're slightly oversized for a tight fit.

Slotted Spring Pin Assortments

Slotted spring pins are also known as roll, tension, split, and expansion pins. Because the slot is pressed closed when the pins are inserted, they don't flex after installation.

Locators, Supports, and Stops

Locating Pins

Install these pins in a plate or table and mate with holes in a workpiece for precise alignment.

Press-Fit Locating and Support Buttons

Support and position workpieces and fixtures from the bottom or side. These buttons press into a drilled hole for permanent installation.

Threaded Locating and Support Buttons

Use these buttons to support and position workpieces and fixtures from the bottom or side. Their hex shape lets you screw them into a threaded hole with a wrench or socket.
