The purpose of a countersink is to allow a fastener, typically a flathead screw, to sit slightly below the surface of the part. Perpendicularity is a fairly common symbol that requires the referenced surface or line to be perpendicular or 90 from a datum surface or line Runout is how much one given reference feature or features vary with respect to another datum when the part is rotated 360 around the datum axis. If you require derived hole standards, you must define these in this file as well. This ebook covers tips for creating and managing workflows, security best practices and protection of intellectual property, Cloud vs. on-premise software solutions, CAD file management, compliance, and more. Surface Perpendicularity is a tolerance that controls Perpendicularity between two surfaces aligned at 90 degrees to each other.
