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.

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.
Copper pins cool faster than steel ones.

Ejector Pins
Also known as knockout and forged pins, use these pins to push parts out of molds. Pins are precision-ground to tight tolerances and hardened for strength and wear resistance. Machining is not recommended.
H13 tool steel pins resist rapid changes in temperature.

Through-Hardened Ejector Pins
Compared to standard ejector pins, these pins are less likely to chip and crack when used to push steel parts out of molds because they've been hardened through their core. However, they cannot be drilled or tapped and are more brittle than standard ejector pins. They're also known as knockout and forged pins. Made of H13 tool steel, they resist rapid changes in temperature. They’re precision ground to tight tolerances.
