Metric DIN 7 parallel dowel pins are solid cylindrical rods made of a variety of materials that are used to strongly and accurately join two or more objects together. Parallel dowel pins are able to join parts together by frictional forces between the pin and material into which it is inserted.

Dowel Pins per. DIN EN ISO 8734. Parallel pins, of hardened steel and martensitic stainless steel. Table gives the characteristics of parallel pins (dowel pins) of steel, through hardened or case hardened and martensitic stainless steel with nominal diameters, d , from 1 mm to 20 mm inclusive.
Dowels are solid pins, usually precision ground to narrow limits to permit accurate fitting, they are traditionally used to hold parts together in a fixed alignment, relying on the tightness of fit to stay in place. Some applications for solid pins require clearance or transition fits on at least one of the components to be. fastened.
