A bolt is a mechanical part with a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread) is required to be fitted with a nut for fastening the two parts with through holes.
The differences in mechanical function requirements for stainless steel bolts and nuts are:
1. The plastic target required by the bolt, the higher the functional level, as long as the higher level of data arrives. The low-level data only needs to reduce the tempering temperature to reach the strength requirement, but it is not satisfied with the plasticity and patience requirements. In the middle, the brittle fracture is judged as unqualified. The steel structural bolts also have a higher tensile strength, which is to ensure the plastic resistance of the bolt.
2. The mechanical function of the nut mainly depends on the hardness of the nut and the height of the nut, and the wall thickness of the nut. Therefore, the requirements for the data are not high. Of course, if the nut is required to withstand the resistance, a higher level of data should be used, for example. Chemical fastener nuts have strict requirements on the resistance to the rules.
