Anyone into metallurgy fracture analysis? What do you gauge from this failure (all four wheel studs went with the same fracture pattern at the same time). No corrosion indicates rapid onset in my eyes. Maybe stretched by over-torquing then fatigued with unidirectional bending very fast?1mo ⋅ keto_drone_flyer ⋅ r/metallurgy
