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.

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.

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.
