Thanks all. I had done extensive reading but with my limited knowledge and comprehension of such matters it was impossible to just get an answer in kg. I’m grateful to Nick for coming up with 750kg, which puts my mind at ease, especially as there are four bolts, and as pointed out the aluminium of the dovetail would likely fail first. Paul, I was worried more about shearing across the bolt than longitudinal force and stripping the threads. It was interesting reading about it all though, and I had no idea it was so involved and different thread counts present different shearing capabilities.
Thanks all!
