Dowel Pin Tolerance Chart

Hardware ANSI Menu | Products and Service Directory
 Mechanical Tolerance Standards Charts

Review your design to determine if you have similar application requirements.  Should these design guideline be inadequate, reference the charts given within the Hole - Shaft tolerance pages.

General

  • 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).

See bottom of page for application  illustrations.
