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.

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.
M2 tool steel pins withstand high temperatures.
Metric pins meet DIN 1530 specifications.

Slotted Spring Pins
Also known as roll, tension, split, and expansion pins, these pins have a slot along one side that you squeeze closed to install them into unthreaded holes. Once installed, they expand slightly, creating outward tension that holds them tight against the hole wall. These pins absorb shock and vibration in your system, and keep parts from loosening. They are often used as hinge pins, or to hold springs and power transmission components in place.
Install these pins into a hole. They have at least one chamfered end, which means the end is angled to make insertion easier.
Breaking strength is measured as double shear, which is the amount of force required to break a pin into three pieces.
Some metric pins with the same diameter come in two different wall thicknesses. Thinner walls are more flexible, easier to install, and won’t weigh down your assembly as much as thicker pins. Layer a pin with a thin wall inside a pin with a thicker wall to increase the breaking strength. Make sure the slots are opposite one another for maximum strength.
Steel pins are strong and wear resistant.
18-8 stainless steel pins offer a balance of strength and corrosion resistance.
Passivated pins offer added protection against corrosion and oxidation.
Pins that meet specifications for ISO 8752 (formerly DIN 1481) or ISO 13337 (formerly DIN 7346) adhere to international standards for pin dimensions.

Coiled Spring Pins


These spiral pins remain flexible after installation, so they absorb shock and vibration better than slotted spring pins. They work well in holes that are out of round. Use them for fastening, pivoting, and holding.
Squeeze pins closed and install them in a hole. Tension holds them tight against the hole wall. The chamfered ends aid insertion.
Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Steel pins offer good strength.
Metric pins meet either ISO 8748 or ISO 8750 specifications.
