Dowel Pins Information - Dowel pins are industrial fasteners that are used to join two or more items together. They are short, cylindrical rods made of various materials including metal,wood and plastic. Dowel pins can be Straight,Tapered in Plain and Internal Thread, Slotted, Grooved, or otherwise altered to change its mechanical properties.They are commonly available in imperial or metric units.
Dowel Production-
Metal dowel pins undergo a melt and cast process, as indicated by the info graphic below:

Common metal materials for dowel pin manufacture include:
- Steel that is hardened and ground is compacted to produce a very hard, though brittle, metal. It has gone through a hardening process such as quenching or induction. Unhardened steel is more malleable, but is still suitable for many applications.
- Stainless steel has a high pressure rating, and is chemical and corrosion resistant.
- Aluminum, which is light, ductile, conductive, and very resistance to oxidation.
- Brass is strong, ductile, conductive, corrosion resistant, and demonstrates low magnetic permeability.
- Titanium is strong, with good temperature and corrosion resistance. It is 44% lighter than steels.
Plastic dowels are formed via plastic injection molding.
Dowel Pin Sizing-
After material, dowel pin sizing is the other major specification manufacturers need to consider.
- Outer diameter is the measurement across the edges that form the dowel pin's width.
- Length is the measurement of the dowel's longest cross section.
Most dowels produced are of the straight dowel variety. A dowel may have diameter tolerances of ± .010 mm compared to the dowel pin's nominal size. This tolerance ensures that the dowel mates in either a loose-fit or press-fit fashion with its corresponding hole. If the pin has two separate tolerances on each end, it is considered a 'parallel pin'.
Configuration-
There is a limited number of dowel pins types. Solid Pins, Internal Threaded, Taper, Taper Internal Threaded have their own unique Competent Engineers selection guide and specification filter.
