Every engineered part, assembly, or machine has a finite service life. Even components boasting the most precise designs executed with proven manufacturing techniques eventually fail. Fasteners are no different. As any engineer will tell you, it’s when these failures are unexpected or premature that they become real problems. So, what causes premature fastener failures? More importantly, what can be done to minimize risks and maximize a fastener’s service life?(…)
