When no tolerance on hole size is called out
When no tolerance on hole size is called out
(OP)
I have a hole callout of .097 dia. with a .002 tp at mmc. Since there is no specific tolerance on the hole size, is it standard practice to use the +/-.005 tolerance in the tolerance block for the drawing? My understanding was that on holes with no tolerance specified fell under some sort of spec where I believe the tolerance for a hole of this size is +.003/-.001 If any one can point me to a spec that shows this, it would be of great help

So, unless the dimension is max, min, basic or stock, or there is a general note specifying the tolerance application, it MUST default to the title block tolerance.

ringman, can you cite the ASME standard that says a hole must have a tolerance on size? Why would a hole be different than any of feature of form?
