Hi, I am designing some frames for motor. According to the company's schematic diagram, the holes are of size M2.5x.45 TAP DP 4.0 (max). Does that mean the diameter of the screw is 2.5mm, screw thread 0.45mm and the max depth of the holes are 4.0mm? When I downloaded the STEP CAD file and checked the holes in SW, they were modeled as holes of diameter 2.05mm. How come? Am I missing some information?
