The invention discloses a method for improving the contact precision of pushing screws small end surfaces in a super nut and a gasket. The method specifically comprises the following steps of 1, a setof pushing screws to be machined are uniformly arranged in threaded holes in the periphery of a super nut before grinding, and a certain pre-tightening force is exerted on the pushing screws so as toprevent the pushing screws from loosening during grinding; 2, an external thread of a grinding tool is installed in the internal large threaded hole in the middle of the super nut with the pushing screws in the step 1 and is pre-tightened, enabling a small step surface of the grinding tool to be tightly attached to the bottom end surface of the super nut; and 3, a whole set of grinding tool to beground after being installed in the step 2 is placed on a workbench, so that the tool positioning surface of the grinding tool is sucked on a grinding machine sucking disc, a grinding machine wheel is used for carrying out unified grinding and machining on the small end surfaces of all the pushing screws, and until all the small end surfaces of the pushing screws are ground.
