Rivet holes dimensions:
As per EN4084, rivet holes tolerance is 0/+0,4 mm.
In QTR, relevant tolerance is 0/+0,2 mm, which is a tighter tolerance.
Rivet holes tolerance 0/+0,2 mm is common anyway.
From my side, I am happy with that, just something to point out and to make sure that no installation issue may occur (i am pretty sure no, but it’s better to check).
Many thanks in advance
Best regards, Julien
On Behalf of Mrs Genevieve Lacombe see below her reply :
QTR 7917 was updated with the right tolerances (0/+0,4 mm) see QTR7917A enclosed
As you wrote rivet holes tolerance 0/+0.2 mm is common on the anchor nut . The manufacturing drawing is based on the common tolerance , which is inside to the EN4084 standard . We never had any feed back from our customer concerning an installation ( see quality letter enclosed ).

Many thanks Mrs Richard, Mrs Lacombe.
All is clear now!
Approved from my side.
Best regards, Julien
