          | 5/16-18 UNC Allied Titanium Hex Nylock Nut, Grade 5 (Ti-6Al-4V) Titanium with Polished Finish |  
          |  |

              |  | These Nylon Insert Hex Locknuts are Grade 5 (Ti-6Al-4V) titanium and are TRUE TITANIUM(TM). They are stronger, lighter and completely corrosion free, even in saltwater. The nylon insert in the hex nut allows for the threads on a bolt or screw to embed themselves into the nylon holding it firm and in place so that it does not loosen from vibrations. These are structural, aerospace grade nuts with a minimum yield strength of 128,000 psi (880 Mpa) while weighing 44% less than steel. 
 TRUE TITANIUM(TM) is a trademark to establish that this product is manufactured from solid Titanium, rather than a coating, plating or color. TRUE TITANIUM, Tough-Ti, the AT Logo, the Ring around our high strength screws, LOOK FOR THE RING, AFFORDABLE TITANIUM NOW and ALLIED TITANIUM are all trademarks of Allied Titanium, Inc.
