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.

Core Pins
Mold plastic around these pins to form small holes, or use them to perforate parts. They have a flat head to fit into a counterbored hole. Pins can be machined to fit your application. They're precision-ground to tight tolerances. Made of M2 tool steel, these pins are wear resistant and stay sharp at high temperatures.
