Dowel Pins

Pins for Shear Hubs

For use with Browning shear hubs, these pins are designed to fail at specific loads to protect heavy duty machinery from torque overload.

Dowel Pins

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

Undersized Dowel Pins

Slip these pins in and out during maintenance or prototyping—they’re undersized to make alignment easier.

Full-Groove Dowel Pins

Grooves run the full length of these pins for a firm hold that won't spin. Use them in place of standard dowel, spring, and taper pins to fasten parts. Also known as type A pins.

Center-Groove Dowel Pins

Center-groove pins are often used in place of clevis pins or to create T-handles. The grooved center locks pins in position, while the smooth ends act as a pivot. Also known as type E pins.

Half-Groove Dowel Pins

These pins make good hinges or pivots. The grooved half locks pins in position, while the smooth half can act as a pivot. Also known as type H pins.

Half-Groove Dowel Pins with Notch

These pins are commonly used as anchors for tension springs. The grooved half locks pins in position, and spring ends fit in to the notch. Also known as type G pins.

Quarter-Groove Dowel Pins

Quarter-groove pins are well suited for hinges or pivots. The grooved end locks pins in position, while the smooth portion can act as a pivot. Also known as type C pins.

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.

Spiral-Vent Pull-Out Dowel Pins

A spiral groove cut into these pins relieves trapped air but stays in 360° contact with the hole for a secure fit that's easy to insert in and remove from blind holes. To remove, thread a screw or tool into the tapped hole, then pull the pin out.

Center-Knurled Dowel Pins

Center-knurled pins are often used in place of clevis pins or to create T-handles. The knurled center locks pins in position, while the smooth ends act as a pivot.

Half-Knurled Dowel Pins

Use these as pivot or hinge pins. The knurled half locks pins in position, while the smooth half acts as a pivot.
