Anyone had the bolts break on their bullbar and if so what do you think caused it?

I have a 2019 Troopy fitted with a popular Australian commercial steel bullbar (I don't like naming brands but it is not ARB).
It developed a squeak so I thought I'd check the bolts and found that the heads of 6 of the M10 8.8 tensile bolts had broken off.
I took the bullbar off and found the 6 broken bolts were not actually clamping metal to metal - there was a 2mm gap between bullbar and chassis when the bolts were done up tight so the bolts were straddling a gap rather than clamping the bullbar to the chassis rail.
The bolts were always torqued to spec - when I fitted it myself and probably sometime since.

My only interest is to fix it and prevent it happening again. I do my fair share of corrugations - the vehicle has done the Canning, the ABH and lots of dirt road trips in outback SA, Qld and NSW.

Anyway I bought new bolts from Hobson to replace all the Chinese bolts and made up steel shims to space out the gaps between the bullbar mounts and chassis rails, so the bolts are doing their job.

Anything else I should do?
