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.

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.

These pins have a low-profile head, so they won't get knocked out of place. A spring-loaded, nonlocking retaining ball pops out when the pin is pushed through a hole, and retracts when the pin is pulled out.

Two spring-loaded balls give these pins more holding power than quick-release pins with only one retaining ball. The balls pop out when the pin is pushed into a hole, and retract when the pin is pulled out.

The extra height and smaller width of the grip make the button more accessible in tight spaces. For a more secure hold than standard quick-release pins, these pins lock in place until you push the button to release the spring-loaded retaining balls.

For the tightest spaces, these narrow-grip pins have the smallest heads of any of our locking quick-release pins. They lock in place until you push the button to release the spring-loaded retaining balls.

Attach these pins to a machine cover or access panel, then clip them in to receptacles installed in the enclosure for quick access. Pins lock in place until you release them.

Retract the nose by pulling the knob.

Quickly align, join, or hold machine components in place in food, pharmaceutical, and other sanitary environments. Pulling the plunger knob and twisting it 90° will lock the nose into its retracted position.

Lock the nose into the retracted position by pulling the handle and rotating it 90°.

Install with a driver.

These spring plungers have a nose that is about three-times longer than standard long hex-nose spring plungers.

Designed with a flange to keep the plunger from being pushed through a hole when the ball is depressed.

Install these spring plungers with a screwdriver—they're slotted on one or both ends.

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.
