Friction has a tremendous impact on bolted assemblies,  a small portion of the applied torque (roughly 10 percent) actually results in useable bolt load available that ends up applied to the gasket; a majority of that torque is consumed by friction between the threads of the stud or bolt and nut or blind hole, and the flange surface under the head of the bolt or nut. That value of useable bolt force can be increased using a more effective lubricant with a lower K factor, which reduces the overall friction effect on the assembly.

Check out the K Factor of Flex-Moly and Flex-Copper.
