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.

All metric pins meet ISO 2338-h8, which means they adhere to international standards for dimensions and tolerances.

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.

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.

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.

Passivated pins offer added protection against corrosion and oxidation.

Metric pins meet ISO 8750 specifications.

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.

Screw the threaded end of these metric studs into a tapped hole and use the unthreaded end as a pivot point, hinge, shaft, or locator pin. All can be installed and adjusted by hand or with a slotted screwdriver. These studs are steel for strength and wear resistance. They’re best for dry environments, since moisture will cause them to rust. All meet ISO 2342 (formerly DIN 427), an international standard for fastener dimensions.
