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.

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.

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.

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.

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.

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.

Stepped Pipe Flange Aligner Pins

Each step on these aligner pins matches common bolt holes on pipe flanges, so they're more precise than conical aligner pins and don’t require nuts. Press the pair of pins into mated flanges to make sure the flanges are aligned.
