Dowel Pins

Use these metal dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts.

Ring-Grip Clevis Pins

Easier to install and remove than standard clevis pins, these pins have a ring-grip handle.

Ring-Grip Quick-Release Pins

The smooth ring handle on these pins won't catch on parts. A spring-loaded, nonlocking retaining ball pops out when the pin is pushed through a hole, and retracts when the pin is pulled out.

T-Handle Locking Quick-Release Pins

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.

Knob-Grip Locking Quick-Release Pins

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.

L-Handle Locking Quick-Release Pins

When there isn't enough room for a T-handle, an L-handle saves space but is still easy to grip. 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.

Adjustable-Length Locking Quick-Release Pins

These pins adjust to take up play in a system or hold parts in holes of varying thicknesses. Spin the handle up or down, then tighten the locknut to change the length by up to ½”. Pins lock in place until you push the button to release the spring-loaded retaining balls.

Expanding Diameter Quick-Release Pins

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

Cotter Pins

Also known as split pins, these have one prong slightly longer than the other so they’re easy to open. Bend prongs outward to secure.

Captive Fastening Pins

Often used in cell phones and laptops, these pins attach thin panels such as printed circuit boards to metal and plastic bases. Also known as PEM® TA and T4 TackPins.

Captive Fastening Pins for Soft Materials

The grooves in these pins grip plastics and other soft materials. Press them in to hold panels together. Also known as PEM® TKA and TK4 TackSert pins.

Thread-In Captive-Panel
Retractable Spring Plungers

Insert the nose into a panel; then thread on the nut and tighten using an installation wrench.

Twist-to-Lock Thread-In Captive-Panel
Retractable Spring Plungers

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

Press-Fit Extra-Long-Nose Spring Plungers

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

Machine Key Stock

Cut this stock to length to create the machine key you need. Straight keys, with a square or rectangular cross section, are the most common type of key. Install in a keyway to transmit torque from shafts to gears and other components.

Pin-Drive Rivets

Hammer the pin into the body and it flares out for a secure hold. These rivets require access to only one side of the material and can be used in through-holes or closed-end holes.

Clamping and Workholding

Locating Pin Retractors

Use the handle on these retractors to extend and retract a locating pin, protecting the pin from damage in applications where fixtures move through a process, such as along a conveyor belt.

Air-Powered Locating Pin Retractors

A good choice for automated clamping, these retractors use compressed air to extend and retract a locating pin, protecting the pin from damage in applications where fixtures move through a process, such as along a conveyor belt.

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.

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.

Create-Your-Own Spring-Loaded Guide Pins

Thread in a screw, handle, or other part to create the right size and shape guide pin for your application.

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 Plungers for Thin Workpieces

Set the tang in a slot below the work surface to prevent thin material from sliding underneath the face.

Ball-Lock Quick-Change Fixture Clamps

Build these components into fixture plates, machine subplates, and tombstones for quick changes. The system clamps and locates at the same time for accurate positioning with repeatability of ±0.0005".

Inspection and Measuring Fixturing

Use these components in coordinate measuring machine (CMM) applications to raise a workpiece and reliably position it on a fixture plate with ¼"-20 holes.

Measuring and Inspecting

Plug Gauge Handles

Add a handle to hold your plug gauge. No need for bushings—one handle fits a range of plug gauge sizes.

Pipe Flange Aligners with Protractor

Line up two pipe flanges and determine pipe angle with the included nut-and bolt pins, level, and protractor.

Nonsparking Marking Punches

Made of aluminum-bronze that is Factory Mutual approved, these nonmagnetic, corrosion-resistant tools inhibit sparking.

Fastening Tools

Nonsparking Hole-Alignment Pins

Made from aluminum-bronze that is Factory Mutual approved, these nonmagnetic, corrosion-resistant tools inhibit sparking. They satisfy OSHA requirements for nonsparking tools.

Double-Taper Nonsparking Hole-Alignment Pins

When one side wears out, use the other one.

Nonsparking Pin-Removal Punches

Made of materials that are Factory Mutual approved, these nonmagnetic, corrosion-resistant tools inhibit sparking. They satisfy OSHA requirements for nonsparking tools.
