Ahmed,

I don't disagree - but that gap is going to be a function of the following:

1. Tie rod bolt circle radius
2. Tie rod flange hole diameter
3. Tie rod diameter
4. Flange thickness

Let's assume the drawing is to scale.

The bolt circle diameter would be 980 mm.
The rod diameter would be 20mm.
The bolt hole diameter would be 25 mm.
The flange thickness is also 20mm.

The angular gap is approximately 7 degrees, which is admittedly surprisingly large.

Seeing that it's using M20 nuts, which are for M20 rods, which are 20mm, it might stand to reason that the drawing is accurate and to scale.

But that's an assumption you should take up with the manufacturer.
