Spring 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.

Long-Nose Spring Plungers

Install with a driver.

Press-Fit Extra-Long-Nose
Spring Plungers

Noses are up to four times longer than standard long-nose press-fit spring plungers.

Press-Fit Long-Nose Spring Plungers

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

Hex-Drive Long-Nose Spring Plungers

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

Slotted Long-Nose Spring Plungers

Slotted on both ends for installation with a screwdriver.

Long Hex-Nose Spring Plungers

Weld these catches in place for a strong permanent hold.

Drivers for Spring Plungers

Install spring plungers from the nose end without depressing the nose.

Mounting Bases for Spring Plungers

Mount ball-nose and long-nose spring plungers to fixture surfaces.

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.

Anchors for Concrete, Block, and Brick

Installation Tools for Shallow-Hole
Female-Threaded Anchors

Drive these tools with a hammer to expand anchors.

Adjustable-Depth Installation Tools
for Shallow-Hole Female-Threaded
Anchors

An adjustable stop allows you to set anchors at consistent depths. Use with a hammer.

Quickset Installation
Tools for Shallow-Hole
Female-Threaded Anchors

The fastest way to install shallow-hole female-threaded anchors. Just push the tip of the tool into the anchor and turn the tool with a power drill.

Easy-Install Female-Threaded
Anchors for Concrete

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.

Steel Female-Threaded
Anchors for Concrete

A zinc plating provides corrosion resistance in wet environments.

Installation Tools for
Female-Threaded Anchors

Drive these tools with a hammer until the thicker portion of the tool makes contact with the anchor, causing it to expand.

Removable-Bolt Anchors for Concrete

Turn the bolt to expand the nut for a secure hold in concrete. These anchors are often used to anchor machinery.

Flat Head Removable-Bolt
Anchors for Block and Brick

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

Female-Threaded Expansion
Anchors for Hollow Block and Brick

For narrow holes and small cavities where toggle anchors won't fit.

Spring-Loaded Guides

Spring-Loaded Guide Plungers

As the face of these plungers is pushed in, the internal spring applies outward pressure to hold a workpiece in position against stops and rails.

Spring-Loaded Guide Pins

As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping.

Installation Tools for
Spring-Loaded Guide Pins

Use these tools for easier guide pin installation.

Threaded Spring-Loaded Guide Pins

Threading makes these guide pins easier to remove and replace than press fit, so they're useful for high-wear applications.
