<p dir="ltr">Hi George<br>
The reason to have at least 50mm is since the eye bolt is screwed to an aluminum alloy part so we need more material to get the required capacity.<br>
60 mm because the tapped hole is not deeper than 60 mm.<br>

The correct hoist ring is on order. But I have a question. What are
the engineering/technical requirements that the length of the M24
bolt must be <60mm and > 50mm?<br>

<br>
the eye bolt suggested by George is fine for us but the length
of the threaded shank ( L in the figure below) MUST be at least
50 mm and less than 60 mm for other reasons.<br>
<br>
The thread in the tapped holes on the RICH part is M24 standard<br>
<br>
We can provide the eye bolt TAW 3 (M24x50) that you can find on
page 145 of the attached pdf file.<br>
<br>
If you already have something similar (Hope Doug has) we can use
it or if you want to procure something similar you can procede
too.<br>
<br>
In any case let us know ASAP what you have decided.<br>
<br>
Many Thanks<br>
<br>
Sandro<br>

This eye bolt cannot be used for the same reason as the other,
it is the wrong lifting device for the job.<br>
