I think stainless would have been ok!!!!!!!!!!!!!!!!!
Based on these figures an M8 bolt, which has a cross section width conservatively of 7mm, has a radius of 3.5mm, and therefore a cross sectional area of 36.75mm2. So, at 700N/mm2 = 25.7kN = 4,250lbs per bolt, it would take in excess of 3.5 TONS of force for the bolts to fail.
Anyone got a right foot that heavy!
May be this is a little flippant, as the failure is likely to be stripping the threads, rather than on the cross section failing?
Anyone any ideas how to calculate that?
Mike
