Unthreaded Inserts

Unthreaded Inserts for Metal

Protect bolts from sideways (shear) pressure.

Steel Unthreaded Inserts for Plastic

A zinc-plated finish gives these steel inserts mild corrosion resistance.

Brass Unthreaded Inserts for Plastic

Made from brass, these inserts are nonmagnetic, mildly corrosion resistant, and electrically conductive.

Aluminum Unthreaded Inserts for Plastic

These aluminum inserts are lightweight, nonmagnetic, and mildly corrosion resistant.

Pins

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.

Vibration-Resistant Slotted Spring Pins

Interlocking teeth help these pins resist sliding when exposed to vibration. They have a slot that presses closed when the pins are inserted so they don't flex after installation.

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.

Heavy Duty Coiled Spring Pins

For tough jobs, these spiral pins are 30% stronger than our standard coiled spring pins. They remain flexible after installation to absorb shock and vibration, and work well in holes that are out of round.

Hollow Dowel Pins

Pass wires and other components through these hollow pins.

Spring Pin Assortments

Slotted Spring Pin Assortments

Slotted spring pins are also known as roll, tension, split, and expansion pins. Because the slot is pressed closed when the pins are inserted, they don't flex after installation.

Coiled Spring Pin Assortments

Coiled spring pins are flexible after installation, so they absorb shock and vibration better than slotted spring pins. They also have higher dynamic load capacities and accommodate wider hole tolerances.
