Dowel Pins

Use dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. For a tight fit, your hole should be equal to or slightly smaller than the diameter shown. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.

Steel pins are the strongest dowel pins. Steel pins are precision ground except for 1/32" diameter pins.

Stainless steel pins are more corrosion resistant than steel pins. Pins that are passivated offer added protection against corrosion and oxidation. Stainless steel pins are precision ground except for 1/64" diameter pins. 18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic. 316 stainless steel pins have the best corrosion resistance of our stainless steel pins. They may be mildly magnetic.

DIN 6325-m6 is functionally equivalent to DIN EN ISO 8734, with slight differences in hardness and length tolerances. ISO 2338-m6 is functionally equivalent to DIN 7 but the ends are chamfered instead of rounded .

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.

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 slightly smaller than the pin diameter. 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.

Pins that meet specifications for ISO 8752 (formerly DIN 1481) or ISO 13337 (formerly DIN 7346) adhere to international standards for pin dimensions.

Captive Pins

Also known as pilot pins, use these pins to position, pivot, and align components. To install, punch or drill a hole in sheet metal, then use a punch and anvil or arbor press to clinch the head to the metal.

Pins are passivated for added protection against corrosion and oxidation. The ends are chamfered for easy insertion.

PEM® MPP pins work with most materials. Made of A286 stainless steel, they're our strongest captive pins, with corrosion resistance comparable to 18-8 stainless steel pins. They are nonmagnetic.
