Stainless Steel 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.

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.

Expanding Diameter Quick-Release Pins

Flip the handle 180° to expand and contract the shaft for a tight, vibration-resistant fit.

Spring Plungers

Knob-Style Retractable Spring Plungers

Retract the nose by pulling the knob.

Twist-to-Lock Knob-Style Retractable Spring Plungers

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

Sanitary Twist-to-Lock Knob-Style
Retractable Spring Plungers

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.

Pull-Ring Retractable Spring Plungers

The ring allows you to attach these spring plungers to a lanyard.

Twist-to-Lock Pull-Ring Retractable Spring Plungers

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

Pull-Ring Retractable Spring Plungers with Lanyard

Use the lanyard as a tether to secure the spring plunger to machinery and prevent accidental drops.

Twist-to-Lock L-Handle Retractable Spring Plungers

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

L-Handle Retractable Spring Plungers

T-Handle Retractable Spring Plungers

Add-a-Knob Retractable Spring Plungers

Thread onto machinery or attach a knob or handle to the threaded spindle.

Low-Profile Knob-Style Retractable
Spring Plungers with Hex Drive

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

T-Handle Weld-Mount Retractable Spring Plungers

A T-handle makes these spring plungers easy to grip.

Twist-to-Lock T-Handle Weld-Mount
Retractable Spring Plungers

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

Ball-Style Weld-Mount Retractable Spring Plungers

A smooth ball handle is easy to grip and won't catch on other parts.

Twist-to-Lock Ball-Style Weld-Mount
Retractable Spring Plungers

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.

L-Handle Weld-Mount Retractable Spring Plungers

An L-handle takes up less space than a T-handle.

Add-a-Knob Weld-Mount Retractable Spring Plungers

Add a knob or handle to the threaded shank.

Plate-Mount Retractable Spring Plungers

Two holes in the plate allow these plungers to be mounted to a flat surface.

Twist-to-Lock Plate-Mount Retractable Spring Plungers

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

Press-Fit Long-Nose Spring Plungers

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

Long-Nose Spring Plungers

Install with a driver.

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.

Slotted Ball-Nose Spring Plungers

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

Press-Fit Ball-Nose Spring Plungers

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

Flush-Mount Press-Fit Ball-Nose Spring Plungers

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

Sealing Press-Fit Ball-Nose Spring Plungers

An O-ring in the flange creates a tight seal.

Hex-Drive Ball-Nose Spring Plungers

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

Weld-Mount Catches for Ball-Nose
and Long-Nose Spring Plungers

Weld these catches in place for a strong permanent hold.

Press-Fit Catches for Ball-Nose Spring Plungers

Press these catches into a hole.

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

18-8 Stainless Steel Female-Threaded
Anchors for Concrete

These 18-8 stainless steel anchors have good chemical resistance.

Super-Corrosion-Resistant 316 Stainless
Steel Female-Threaded Anchors for Concrete

More corrosion resistant than 18-8 stainless steel anchors, these 316 stainless steel anchors have excellent resistance to chemicals and salt water.

Hex Head Removable-Bolt Anchors for Block and Brick

A hex head allows for a secure grip with a wrench.

Sealed Spring-Loaded Guide Pins

Sealed at the top to prevent debris from getting inside and making them seize up, these guide pins are a good choice for machining fixtures.
