I have friends with quickdraws that are over ten years old and the biners are still perfectly serviceable (if not a bit heavy by modern standards). The dog bone is the real weak point and those I mentioned have had new ones, keeping them going for another 10+ years if required. | |

| Oct 26, 2022 at 22:01 | comment | added | Mark | @Andrestand, 0.2mm is plenty. 316L stainless is extremely ductile; under a sudden load, the edges will deform to match the curve of the carabiner, greatly increasing the contact area. | |

The surface area in contact with the biner, given its typical rod radius, is less than a square mm, so shear stress exerted by the plate on the biner when loaded is not small. The same for bending stress, as this single and small contact point is about 2 cm far from the ends of the upper, horizontal shaft of the carabiner, where the downwards force is exerted. The point is if slightly heavier and expensive plates wouldn't compensate by far the lifetime extension for what we connect there. | |
