Yes—Auto-Lok supplies titanium MJ-thread prevailing-torque nuts for demanding aerospace applications. Titanium offers a high strength-to-weight ratio and corrosion resistance, while the MJ thread profile improves fatigue performance with its larger root radius and aerospace tolerance classes.
- Material: aerospace-grade titanium (lightweight, corrosion-resistant).
- Thread form: MJ (metric aerospace) with typical internal classes 4H6H / 4H5H.
- Locking: reusable, all-metal prevailing torque (no nylon insert).

When to choose titanium MJ nuts
Select MJ when your drawing calls the MJ profile or when fatigue resistance at the thread root is critical. Always pair MJ internal with MJ external threads. For installation, use the joint’s calculated tightening torque (based on bolt size, property class, and lubrication) and verify prevailing-torque compliance per your specification.
