ABSTRACT:
The present invention provides a threaded member with antirust effect. An oil reservoir is formed inside the threaded member and multiple conduits are formed on an outer circumference of the stem body of the threaded member in communication with the oil reservoir. An absorption material is installed in the oil reservoir and soaked with an antirust liquid. The antirust liquid in the oil reservoir can slowly seep out of the conduits to the outer circumference of the stem body so as to protect the threaded member from rust.
