Thanks guys,

It's a square taper bottom bracket with a set of Middleburn rs1's.

I really hope not as I love the cranks!

@mdcc_tester

I'll try using different bolts and tighten them more.

Do people grease them or thread lock?

tighten them more.

Tighten them right. Square taper is very sensitive to correct assembly, since the whole function is dependent on stretching the crank boss enough to prevent zero flank pressure under load, but not so much that the pressure on the opposite corner exceeds the yield stress.
