Known for their usefulness in the aerospace industry, titanium grade 7 lock nuts provide lightweight, durability, and resistance to loosening due to vibration and torque.

Titanium Grade 7 is mechanically and physically equivalent to Grade 2 except with the addition of the interstitial element palladium. This gives our Titanium Grade 7 lock nuts enhanced crevice corrosion resistance at low temperatures and high pH. Titanium Grade 7 is the most corrosion resistant alloy in the titanium grades.

These lock nuts are also strong and lightweight, like their Titanium Grade 2 and 5 predecessors, and can be used in oil and gas, military, and sporting goods applications.
