This serves to distribute the pressure to a larger bearing surface of the nut over the part being secured, reducing the chance of damage to the part. These flange nuts are Grade 5 (Ti-6Al-4V) titanium and are TRUE TITANIUM(TM). They are about 3 and a half times stronger than stainless steel, 44% lighter and completely corrosion free, even in saltwater. These , aerospace grade nuts have a minimum yield strength of 128,000 psi (880 Mpa). If you are a race car driver, these are the flange nuts you want holding your car together. If you are a sailboat cruiser, these are the nuts you want holding your rig up.
