Heritage Industrial Cotter Pins & Wire Forms
Dowel Pins
Dowel pins are a category of parts that is the subject of frequent confusion among designers, engineers, buyers, and purchasing departments. There are an abundance of end designs, micro-finishes, and features that complicate matters. There is one prevailing standard in imperial sizes, the ASME B18.8.2, and DIN standards for metric sizes.
