Dowel Pins

Dowels are solid pins, usually precision ground to narrow limits to permit accurate fitting. Precision dowels are traditionally used to hold parts together in a fixed alignment relying on the tightness of fit to stay in place. However, some applications for solid pins require clearance or transition fits on at least one of the components to be fastened.
