Half-Groove Dowel Pins
Dowel Pin
Dowel Pin with Tapered Groove
Dowel Pin with Reverse Tapered Groove
These pins make good hinges or pivots. The grooves pinch shut when pressed into a hole, creating tension and holding the pin in place. The grooved half locks pins in position, while the smooth half acts as a pivot. For the best fit, the hole should be equal to or slightly larger than the diameter shown. The ends are chamfered for easy insertion. Pins are made of zinc-plated steel for good strength and some corrosion resistance. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces. Also known as type H pins.
Tapered pins are good when part of the assembly must be a free fit.
Reverse-tapered pins are useful when the ungrooved portion will act as a stop or handle.
