Solid Pins are common fasteners used for aligning, joining and assembling multiple components. Solid Pins are most useful where the clamp load of a bolt is not needed. They are also used for specifi c functions such as locating components, hinges, tamper-resistant designs, etc.
Two common manufacturing methods used to produce Solid Pins are cold heading and machining. Cold heading and machining both produce high-quality, consistent parts. Interestingly, many outside diameter (OD) ground dowels are not actually machined.
It is common to pass cold headed blanks through a secondary grinding operation in order to produce the OD ground dowels.
