Is the length of a steel dowel pin standardized to a certain tolerance? McMaster-Carr provides tolerances on the diameter of dowel pins but not the length. In the event where I want a dowel pin to fit into two blind locating holes, I'd like to know if I need to leave a little extra "wiggle room" in the hole depth.
For example, I have two parts that need to meet as close together as possible. One part has a 5 mm deep locating hole for a dowel pin. If I have a 10 mm dowel, can I specify a 5 mm deep locating hole on the second part (assuming the dowel is actually <10 mm long)? Or should I choose something deeper (5.5 or 6 mm perhaps)?
