Locating Pins
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 pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.

Shoulder-Style Locating Pins
The shoulder provides a consistent height reference point and keeps the pin from being pressed through the fixture. 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 pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.

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

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.
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.
