Locating Pins

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

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.

Shoulder-Style Locating Pins

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

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.

Threaded Locating Pins

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

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.
