Pins

Clevis Pins

The low-profile head on these pins holds them in place on one side.

Adjustable Clevis Pins

Also known as universal clevis pins, these pins have holes on 1/4" centers so you can change the length by moving the cotter pin.

Precision Clevis Pins

These pins combine the locking capabilities of a clevis pin with the precision diameter of a dowel pin for a tight fit.

Headless Clevis Pins

Install or remove these pins from either side.

Adjustable Bent-Pull Clevis Pins

These pins have multiple through holes; change the length by moving the cotter pin. The bend makes them easy to insert and pull out.

Bent-Pull Clevis Pins

The bend makes these pins easy to insert and pull out.

Ring-Grip Clevis Pins

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

Loop-Grip Clevis Pins

A large loop handle makes these pins easy to grip.

T-Handle Clevis Pins

A plastic-coated T-handle welded to these pins makes them easy to grab.

Padlockable Clevis Pins

Use a padlock to secure these pins. The bend makes them easy to insert and pull out.

Made-to-Order Pins

Choose a material, head type, end type, and size to create a custom pin.

Flat-Head Made-to-Order Pins

Create a custom headed pin with your choice of material, dimensions, and end type.

Ball-and-Cotter Double-Locking Quick-Release Pins

These pins lock in place until you push the button to release the spring-loaded retaining balls, and can also be secured with a cotter pin for longer-term holding. Two-step locking prevents accidental removal.

Clevis Pin Assortments

Clevis pins have a hole for a cotter pin on one end to lock them in place.

Locating Pins

Mating Locating Pins and Hole Liners

Maintain consistent alignment in mating parts by installing a pin in one part and a liner in the other.

Locating Pins

Install these pins in a plate or table and mate with holes in a workpiece for precise alignment.

Shoulder-Style Locating Pins

The shoulder provides a consistent height reference point and keeps the pin from being pressed through the fixture.

Threaded Locating Pins

Screw the shank into a threaded hole for quick installation and removal.

Removable Locating Pins

A slightly undersized shank makes these pins easy to install and replace. Also known as slip-fit and lock-screw locating pins, they are held in place by a separate lock screw.

Cast-In Locating Pins for Plastics

Encase these pins while molding plastic or composite parts. Once set, the knurls resist movement, letting you align the workpiece with precision on a plate or table.

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.

Floating Locating Pins

The head on these pins slides side-to-side in one direction. Use one of these pins and one standard round-head pin to prevent jamming when loading and unloading workpieces with inconsistent hole spacing.

Spring-Loaded Guide Pins

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 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.

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.
