Good quality but the M3 holes are slightly off angle

Good quality metal with edge folds for rigidity. Assembled some custom rack panels with these and Neutrik connectors but found that the M3 holes in this panel were slightly rotated from the angle required to get the connector square to the edge - the same on 3 of these panels. Also the D25 is slightly low to the bottom fold to get a nut spinner in there for tightening the nut, which risks deforming the hex slot in an M3 hex countersunk bolt.
