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. 416 stainless steel pins are more wear resistant than other stainless pins, but not as corrosion resistant. They are magnetic.

Plastic Dowel Pins
Plastic pins are a nonconductive and nonmagnetic alternative to metal dowel pins, so they're useful in electronic applications. Use them as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts.
Acetal plastic and PTFE plastic pins are slippery, so they make excellent pivots. Acetal pins resist wear.

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.

Flush-Mount Core Pins
A 60° beveled head fits into a countersunk hole. Mold plastic around these pins to form small holes, or use them to perforate parts. Also known as perforator, mold, forged, quill, and pilot pins, they can be machined to fit your application. Pins are 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.
For technical drawings and 3-D models, click on a part number.
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.
Steel pins are strong and wear resistant. Pins with a black-phosphate or zinc-plated finish have an outer layer to protect the steel underneath from rust.
18-8 stainless steel pins offer a balance of strength and corrosion resistance.
420 stainless steel pins are as strong and wear resistant as steel, with the addition of corrosion resistance in wet environments.
Passivated pins offer added protection against corrosion and oxidation.
Pins that meet ASME B18.8.2 specifications are made to ASME standards for material and 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 slightly smaller than the pin. 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.
420 stainless steel pins resist wear as well as corrosion. They are magnetic.
Passivated pins offer added protection against corrosion and oxidation.
Inch pins meet ASME B18.8.2 specifications for material and dimensions.
