    Barbed Dowel Pins with Rounded Head

    Image of Product. Front orientation. Dowel Pins. Rounded Head, Barbed Shaft, Standard Tolerance.
    Often used in place of rivets, these pins create a finished look while securing plastics and soft metals such as aluminum. The sharp points bite into parts for a permanent hold. Also known as Barb-Lok™ pins.
    Steel
    Zinc-Plated Carbon Steel—These pins withstand occasional exposure to moisture. However, since friction from moving parts can wear away the finish, they're not ideal for wet environments. While not nearly as corrosion resistant as stainless steel, they are stronger and won’t deform under stress.

    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.

    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.
