Usage

Dowel Pins have many types due to the chamfer difference.  The chamfer ends can be both R(Radius) type or both C type or one ends with C and the other end with R.  Some others also have rounded ends.  It depends on the standard accorded and application request.

​

For the body diameter, there are also many different of the standard series and over size series.  Normally, the dia. tolerence can be smaller from +/-0.0001” to +/-0.001” bigger.

​

AS for the hole to be installed.  It’s very hard to determine the hole dimension tolerence.  It may depend on the pins and assembling material hardness.  How tightness of fitting hole is also very important.
