Specifications

The Detroit Diesel 14L Turbo Nut (DDE/23531401) is a specialized OEM fastener built to meet the rigorous standards of commercial diesel engine applications. Featuring a 12‑point flanged design and M10 x 1.5 thread size, this nut delivers exceptional clamping reliability where vibration and thermal cycling are common. Manufactured from high‑strength steel with ASTM 194 Grade 7 classification, it resists deformation and loosening under load. Its flange spreads load evenly across mating surfaces, reducing stress and enhancing joint stability. Ideal for use on Detroit Diesel Series 60 14L engines and compatible heavy trucks.
