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.

Polycarbonate plastic pins have excellent impact resistance. Use them where pounding and flexing could crack other plastic. They're clear for inconspicuous fastening.

PEEK plastic pins are an alternative to metal pins in high-temperature, high-stress applications. They resist chemicals, wear, and moisture.

Slip these pins in and out during maintenance or prototyping—they’re undersized to make alignment easier. Unlike standard pins, which fit tightly inside holes, these are designed to give you some wiggle room. Chamfered ends make them easier to insert. The breaking strength listed is double shear, which is the amount of force required to break a pin into three pieces.

Steel pins are very strong. They are best for dry environments.

18-8 stainless steel pins can be used in wet and humid environments without rusting, but they are not as strong as steel. Pins that meet MIL-P-21143/2 conform to material and dimensional standards created by the U.S. military.

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.

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.

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.

316 stainless steel pins have the best corrosion resistance of our stainless steel pins, and are as strong as 18-8 stainless steel pins.

400 series stainless steel pins resist wear from abrasion and have some 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.

Pins that meet MS16562 conform to military standards for material and dimensions.

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.

18-8 stainless steel pins resist corrosion better than 420 stainless steel pins. They may be mildly magnetic.

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.
