Sustainability in product development emphasizes the need for extended product lifetimes to minimize replacements and reduce resource consumption and environmental impact. This study investigates the impact of different thread manufacturing processes, cutting, rolling, and deep rolling, on the fatigue resistance of M12 threads fabricated from quenched and tempered chromium‐molybdenum alloy steel. Fatigue tests conducted under cyclic tensile loading revealed that rolled threads exhibited superior performance, enduring higher stress levels without failure. Deep rolling significantly increased the fatigue strength compared to cutting, demonstrating its efficiency as a post‐processing technique for enhancing durability. These findings highlight the sustainability and reliability of rolling as well as deep rolling processes and show that deep rolling is an effective post‐processing technique for improving the durability of cut threads.
