Titanium Grade 7 hex nuts are lightweight and highly durable making them the hex nut of choice for the aerospace industry.

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 hex 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 hex 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.
