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.

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.
