The gap has closed up considerably under tension, but there is still a gap there and the load will still be sitting on 2 points rather than spread around the curve of the toggle/pin
.
The brand - "Searig"
The strength of the screws was the "BL (kg)" that is listed in both the Searig and Ronstan catalogues.
Here is a photo of the toggle under tension when installed as a lower shroud.

I did return one swage toggle for a 1/4" wire that had the clevis pin skewed off at an angle as Joe mentioned in his comment on the turnbuckles. Something going on with these toggle plates, wonder if there is subcontracting happening. They used to have Searig stamped on them but these do not.
