Dowel Pin Tolerance ChartGeneral
Typical material is 6061-T651, per QQ-A-250/11 or similar aluminum alloy for the base mating components.
Dowel Pin - are stainless steel 304, 306, 18-8 etc. or similar.
Application - These fits are for location or alignment applications between two components. Some shear load is acceptable, designer should determine acceptable stress limits for their particular application.
These fits are not line-to-line . Fixed fastener calculations will show minimal interference between dowel pins and slip fit holes. Dowel pins should be installed into press fit holes after finishing processes and not removed there after. After the mating components are assembled the first time, one should note assembly orientation for repeat assembly of mating dowel pins. It is optimal to design for one configuration assembly (fool - proof).
