Product Description

Metal dowels or dowel pins/Roll Pins are often used as precise locating devices in machinery. Steel dowel pins are machined to tight tolerances, as are the corresponding holes, which are typically reamed. A dowel pin may have a smaller diameter than its hole so that it freely slips in, or a larger diameter so that it must be pressed into its hole (an interference fit).

There are a variety of specifications, military, ISO, DIN, ASME that pins may be made to. And size can even vary by dowel pin material. Metric dowel pins are often found in two size. In DIN 6325 standard the dowel pins are slightly larger than the nominal value. For example a 3 mm dowel pin will range from 3.002 to 3.008 mm (0.1182 to 0.1184 inches). In the ISO 2338 standard the dowel pins are slightly smaller - 3 mm nominal range is 2.986 to 3.000 mm (0.1176 to 0.1181 inches). The terminology (e.g. "oversized", "standard") is not entirely consistent across suppliers. In inch pins "oversized" refers to pins that are more significantly oversized for worn out dowel pin holes. The most common inch sized pins are slightly oversized, and "undersized" versions are also available.
