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.
