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. The grooves pinch shut when pressed into a hole, creating tension and holding the pin in place. For the best fit, the hole should be equal to or slightly larger than the diameter shown. The ends are rounded 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 G pins.
