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.

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

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

Install by hand or with a hex key in low-clearance applications.

A quarter turn of the handle locks these plungers in the retracted position. The T-handle is easy to grip.

A quarter turn of the handle locks these plungers in the retracted position. The smooth ball handle is easy to grip and won't catch on other parts.

Add a knob or handle to the threaded shank.

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

Lock the nose in the retracted position by pulling the knob and rotating it 90°.

Lock the nose in the retracted position by pulling the knob and rotating it 90°.

A flange keeps the plunger from being pushed through a hole when the ball is depressed.

Install with a hex key for more torque than slotted long-nose spring plungers.

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

The flangeless design allows these spring plungers to mount flush with a surface.

Install with a hex key for more torque than slotted ball-nose spring plungers.

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.

Drive these tools with a hammer to expand anchors.

A zinc plating provides corrosion resistance in wet environments.

Install like a stud anchor—just thread the anchor, a nut, and a washer onto the end of a threaded rod, drive into a hole, and turn the nut to expand the base. Also known as rod anchors, they're often used with threaded rod to hang pipe and wiring.

Bolts are beveled under the head for a flush finish in countersunk holes.
