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.
Metric pins meet DIN 1530 specifications.

Shoulder-Style Ejector Pins
A thick shoulder underneath the head makes these pins more rigid than standard ejector pins. Also known as knockout and forged pins, use them to push parts out of molds. They're precision-ground to tight tolerances and hardened for strength and wear resistance. Machining is not recommended.
Pins are made of H13 tool steel to resist rapid changes in temperature.
