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. Because these pins are knurled all the way around, they distribute twisting forces more evenly than grooved pins. The ends are chamfered for easy insertion. Pins are made of steel for good strength. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Knurled Dowel Pins
Knurls go all the way around the pin to distribute twisting forces more evenly than grooved pins. Pins are made of steel for good strength.

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. Because these pins are knurled all the way around, they distribute twisting forces more evenly than grooved pins. The ends are chamfered for easy insertion. Pins are made of steel for good strength. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Two-Way Barbed Dowel Pins
Use these pins to fasten components made of soft materials such as plastic or aluminum. Opposing barbs bite into each piece, pulling them together for a tight, secure fit. The ends are chamfered for easy insertion. Pins are made of zinc-plated steel for good strength and some corrosion resistance. Also known as Barb-Lok™ pins.

Round Head Barbed Dowel Pins
Barbs bite into plastics and soft metals such as aluminum for a strong hold, and a round head gives a finished appearance. The end is chamfered for easy insertion. Pins are made of zinc-plated steel for good strength and some corrosion resistance. Also known as Barb-Lok™ pins.

Round Head Full-Groove Dowel Pins
A head gives these grooved pins a finished appearance and distributes loads over a wider area than headless pins. The grooves pinch shut when pressed into a hole, creating tension to lock pins in place. For the best fit, the hole should be equal to diameter (A). The end is chamfered for easy insertion.
Pins meet ASME B18.8.2 specifications for material and dimensions. They're made of zinc-plated steel for good strength and some corrosion resistance.
