Important considerations for rivet nuts include the following:
Connection strength: the tensile force, shear force and torsion moment required to determine the connection point of the rivet nut.
Thread size and friction coefficient: The threads of mainstream rivet nut products on the market range from M3 to M12, and there are also inch threads, which need to be selected according to the connection requirements. At the same time, the friction coefficient range of the nut is also specified according to the company's internal specifications.
Plate thickness: The rivet nut should be selected to ensure that the thickness of the plate is within its clamping range.
Hole size: The manufacturer specifies the mating hole size for the rivet nut. You can refer to the manufacturer's design information. At the same time, the coating thickness of the board should be considered to avoid the hole becoming smaller after coating and making it unsuitable for installation.
Materials and surface treatment: The material of the rivet nut can be free-cutting iron or free-cutting stainless steel. Among them, the S series rivet nuts are made of free-cutting iron and have been heat-treated; while the CLS series rivet nuts are made of free-cutting stainless steel and have an untreated surface. The surface treatment of rivet nuts is also one of the considerations, and can be galvanized, chrome plated, etc.
Usage environment: The usage environment is also an important consideration when choosing rivet nuts. For example, in harsh environments such as high temperature, low temperature, and corrosion, rivet nuts with corresponding special properties need to be selected, such as high temperature resistance, low temperature resistance, corrosion resistance, etc.
Installation and removal: Installation and removal of rivet nuts is also a consideration. Generally speaking, rivet nuts need to be installed from the "disconnected" side of the plate. The installation process is usually achieved through a "riveting" operation and should not cause impact.
In general, when selecting a pressure rivet nut, multiple factors need to be considered, including connection strength, thread size and friction coefficient, plate thickness, hole size, material and surface treatment, use environment, and installation and disassembly. Only by selecting the appropriate rivet nut according to actual needs and specific conditions can the quality and safety of the connection be ensured.
