Round Head | Diamond Head |
Install these pins in a plate or table and mate with holes in a workpiece for precise alignment. Press the shank into a drilled hole for permanent installation.
Diamond Head—Diamond-head pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.

Diamond Head |
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 lock screw (sold separately). Mate pins with holes in workpieces for precise alignment. The shoulder provides a consistent height reference point.
Diamond Head—Diamond-head pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.

Floating Locating Pins
 |  |
Head Slides Side-to-Side |
The head on these pins slides side-to-side. Use one of these pins and one standard round-head pin to prevent jamming when loading and unloading workpieces with inconsistent hole spacing.

Cast-In Locating Pins for Plastics
 |  |
Round Head | Diamond Head |
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.
Diamond Head—Diamond-head pins make less contact with the inside of a hole than round-head pins, reducing sticking and jamming. Locate a workpiece using one of each head type for smooth loading and unloading.
