5mm Dowel Pins | McMaster-Carr

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.

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.

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.

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.

Ejector 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.

Heavy Duty Coiled Spring Pins

For tough jobs, these spiral pins are 30% stronger than our standard coiled spring pins. They remain flexible after installation to absorb shock and vibration, and work well in holes that are out of round.

Captive Pins
