Differences between through-hole and closed end rivet nuts

Definition and characteristics of through-hole rivet nuts:A through-hole rivet nut is a connector that inserts the rivet nut into the workpiece through the hole and fixes it by pressurizing the nut. It is characterized by the diameter of the through hole being more significant than the diameter of the head of the rivet nut; the rivet nut can be inserted from the ends of the through hole, and the nut can be installed on both sides of the workpiece, and the assembly and disassembly of the connector is convenient. In engineering, through-hole rivet nuts are commonly used in thin plate connection, pipe fixing, and lightweight structure assembly, with broad applicability, easy installation and disassembly, and other characteristics.

Definition and Characteristics of Closed-End Rivet Nuts:A closed-end Rivet nut is a connector that inserts the rivet nut into the workpiece through the groove at the bottom of the hole and fixes it by pressurizing the nut. When assembling the blind rivet nut, it is necessary to insert the rivet nut upside down into the groove at the bottom of the hole and then pressurize and fix it with the nut.

The characteristics of the closed-end rivet nut are: compared with the through-the-hole, it has a smaller hole diameter, is suitable for use in the back of the workpiece, can not be operated, or the workpiece thickness is limited; the installation needs to be inverted insertion; as well as the need to be repeatedly tightened when pressurized, may be determined by the strength of the material at the bottom of the hole.

Application of the two types of rivet nuts:Through-hole and blind rivet nuts have their advantages; the two types of rivet nuts in the project application are also different. Through hole, rivet nut is suitable for the workpiece material is not restricted or the installation of the need for repeated disassembly of the situation, such as vehicles, ships, aircraft, and other large machinery and equipment connection and fixation; and blind hole rivet nut is suitable for the back of the workpiece can not be operated or the installation of the space is limited in the case, such as electronic equipment, instrumentation, and other small machinery and equipment connection and fixation.
