Mechanical plating forms a dense coating on the surface of rivets through a cold welding process of metal microparticles. Its unique deposition method results in a coating with uniform granular protrusions.
The temperature and humidity in the production workshop must be controlled within a stable range to avoid dimensional changes in materials due to thermal expansion and contraction.
As a classic non-removable fastening element, round head rivets, with their reliable connection performance and excellent vibration resistance, are still widely used in critical components.
Multiple tempering processes can also reduce the performance degradation of screws caused by stress relaxation during long-term use, thus extending their service life.
When subjected to load, stress concentrates at the conical edge, which can easily lead to localized deformation or crack propagation.
In practical applications, ensuring the low-temperature toughness of carbon steel hexagonal bolts needs to be maintained throughout the entire process of design, manufacturing, and installation.
