I apologize in adavance if this is a silly question but I am just starting to understand the ISO 286 standard and would really appeciate some help with a question I am trying to answer.
I am creating an assembly which uses an off the shelf linear actuator with a 4H7 hole for locating. The 4mmx10mm SS dowel pin my company currently uses from McMaster has a tolerance of +0.004mm to +0.012mm so therefore a tolerance zone of m6. I would like to create a hole in which to press fit the dowel pin.
So two questions:
1. Obviously the 4H7 hole in the actuator will provide a clearnace fit with the 4m6 pin but is there a tabel similar to the preferred fit tables in ANSI B4.2 or similar which states this verbally "Clearance"
2. What would be the best method of choosing a tolerance zone for the hole in which to press the 4m6 pin into? Is there a table similar to the preferred fit tables in ANSI B4.2 where I could look to and see a "Clearance" tolerance zone for the provided 4m6?
Thanks in advance all.
