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.

To fit in holes that have widened from wear and are too big for standard ejector pins, these pins are oversized. Also known as knockout and forged pins, they’re used to push parts out of molds. These pins are H13 tool steel, so they resist rapid changes in temperature. They’re hardened for strength and wear resistance and precision ground to tight tolerances. Machining is not recommended.
