When a hole is created for a bolt, it might be "tight"; the intent is for the hole to be tapped. Or it might be "loose", and the intent is for the bolt to slide into the hole and attached to a nut on the other side.

What is the terminology for these two kinds of holes?

  • $\begingroup$ Hey Oscar, I'm getting ready to ask a question about compensating for hole sizes when 3d printing and wanted to make sure I asked properly about a clearance hole (the "loose" one in my ignorance!). If you think it's better to move, that's fine with me. $\endgroup$ Jun 30, 2020 at 3:11

A hole designed for a screw/bolt to slide freely through is called a clearance hole. A hole that is designed to be tapped could be called a pilot hole.
