Jason explains how chamfers and edge breaks are dimensioned and what tolerances apply under ASME standards when none are specified in the field of view.
When applying position tolerances to countersunk fixed fastener assembly conditions, our design must not only ensure assembly, but also that the fastener head sits flush or below the surface of the part. We are able to determine the values required to achieve this by using the fixed fastener equation.
Specifies the angle and diameter of a countersunk hole. Commonly paired with a depth or diameter dimension for fastener seating.
