In this paper, the main research is the finite element modeling and strength analysis of the anti-rust bolts with oil reservoir and helical groove, and obtain its bearing capacity by finite element method. In the finite element software, an indirect method is used to build the helical entity, which can obtain the finite element mesh with better quality. The finite element simulation was carried out by using the progressive failure analysis and the maximum stress criterion, then compares its results with the results of the non-progressive failure analysis. Simulates by using the method of reduction calculation in order to consider the influences of bolt’s strength caused by the groove at the same time, and compares reduction calculation results and the original results and analysis. The results of the finite element calculation shows that the results of the progressive failure analysis and the maximum stress criterion are smaller than the results of the non-progressive failure analysis, The results of reduction calculation are similar to the original results.
