Titanium Grade 5 heavy hex bolts offer exceptional corrosion resistance and are unaffected by most marine environments.

These bolts are resistant to seawater up to 500°F and are shown to last almost two decades in tests of polluted seawater. Additionally, they show no signs of pitting and crevice corrosion even when one mile below the surface. The Titanium Grade 5 heavy hex bolts are also resistant to erosion up to a velocity of 120 feet/second lending them well to the aerospace and aircraft industries.

Titanium Grade 5 heavy hex bolts resist attack by pure hydrocarbons and most chlorinated and fluorinated hydrocarbons provided there is no acid contamination. They are also fully resistant to solutions of chlorides, marine, chlorates, perchlorates and chlorine dioxide making them ideal for the paper industry.

Titanium Grade 5 is 6% aluminum and 4% vanadium. Its strength-to-weight ratio is four times stronger than 316 stainless steel at nearly half the weight.
