Shoulder-Style Locating Pins

Round Head

Diamond Head
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.
