Closed End Rivet Nut Specifications Characteristics Usage

Closed-end rivet nuts and threaded ends are closed blind hole states, and riveted metal sheet metal can play a specific role in waterproofing. A closed-end rivet nut is widely used in automobiles, aviation, instruments, furniture, decoration, and other electromechanical and light industrial assembly. To solve the sheet metal, thin tube welding nut easy to melt, tapping the internal thread easy to slip teeth and other shortcomings of the development, it does not need to tap the internal thread, do not need to weld the nut, riveted firmly and efficiently, easy to use. A closed-end rivet nut is a joint connecting element in various mechanical equipment and structures. It is simple, convenient, and reliable, can quickly complete the connection operation, and improves production efficiency.

Handling of Closed-End Rivet Nuts

The closed-end rivet nut is a specially designed connecting element that allows installation to be accomplished without being able to operate from the other side. It usually consists of a metal sleeve with an internal thread and an externally rotatable tie rod. By inserting the Closed End Rivet Nut into a pre-drilled hole and by tightening the tie rod, connections to other components can be made.

Closed-End Rivet Nut Specifications

1. Dimensions: The dimensions of closed-end rivet nuts vary depending on the application requirements. Generally, their diameters range from M3 to M12, and their lengths range from 10mm to 30mm. The specific size can be customized according to the actual needs.

2. Material: Closed-end rivet nuts are usually made of high-quality stainless or carbon steel. Stainless steel has good corrosion resistance and is suitable for wet or high-temperature environments. Carbon steel has high strength and hardness, which makes it ideal for the general mechanical structure of the connection.

3. Surface treatment: to improve the surface quality and corrosion resistance of the closed-end rivet nut, often its surface treatment. Joint surface treatment methods include nickel plating, electro-galvanizing, hot dip galvanizing, etc. These treatments can effectively extend the service life of the closed-end rivet nut and improve its appearance quality.

Usage of closed-end rivet nuts

Since closed-end rivet nuts can only be installed from one side, they are suitable for the following scenarios:

1. The material does not support the reverse side of the bolt, e.g., closed structures, enclosed spaces, recessed structures, etc. The material can be installed from both sides.

2. The material is thin and not suitable for screws or bolts. Bolts or screws can pass through the entire material

3. The installation process cannot be accessed from the opposite side of the material. A connection structure using rod bolts is required.

4. Drilling: Before using closed-end rivet nuts, it is first necessary to drill holes in the connection area. The diameter of the drilled holes should match the diameter of the closed-end rivet nut to ensure a solid connection.

5. Installation: Insert the closed-end rivet nut into the pre-drilled hole and ensure enough clearance between the nut and the hole wall. Then, tighten the nut by rotating the pull rod until it is tightly connected to the other parts.

6. DISASSEMBLY: If it is necessary to disassemble the closed-end rivet nut, reverse the rotation of the pull rod. Before loosening the nut, ensure the tie rod is loose to avoid unnecessary damage.

Advantages of Closed-End Rivet Nuts

1 Convenience: Closed-end rivet nuts can be installed without being able to operate from the other side. This makes making connections in tight spaces or unique environments easier and faster.

2 HIGH STRENGTH CONNECTION: The closed-end rivet nut adopts an internal and external linkage design, which can provide high connection strength. It can withstand large loads and maintain a stable and reliable connection.

3 Reusable: The closed-end rivet nut can be reused compared to disposable connecting elements. Loosen the tie rod and remove the nut to reinstall it in another location.

Closed-End Rivet Nuts Application Areas

1. Closed-end rivet nuts are divided into sizeable countersunk head blind rivet nut, small countersunk head rivet nut, flat head closed end rivet nut, round head closed end rivet nut, full hex closed end rivet nut, half-hex closed end rivet nut, stainless steel closed end rivet nut and so on according to the type of the head. There are also two kinds of knurling and non-knurling. A closed-end rivet nut is easy to use, has no noise, has a beautiful appearance, and is a good substitute for the traditional welding nut process. At the same time, the installation takes up little space, and a small space to complete the operation is more convenient than installing welded nuts and pressure rivet nuts.

2. Closed-end rivet nuts are widely used in producing automobiles, ships, elevators, and other interior parts. The primary role is the connection of the plate. The rivet nut can be decorated in a single Hublot sheet, but two sheets of paper can also be riveted together, both rivet and rivet nut. It also applies to only one-sided operation of the closed shape of the workpiece; in addition, for the need to screw pastor coupling curve light metal material workpiece, the steel rivet nut is a compact structure, the use of a convenient screw sleeve. Beautiful appearance, easy to use, sheet metal rivet nut is a low-consumption and efficient fastener.

Closed-end rivet nuts are widely used in various mechanical equipment and structures. For example, automotive manufacturing, aerospace, and electronic equipment require closed-end rivet nuts for connections. They can be used for securing seats, mounting instrumentation, connecting metal plates, and more. Closed-end rivet nuts are essential in various industries as a commonly used connecting element. This paper introduces the specifications of closed-end rivet nuts and their use, including dimensions, materials, surface treatment, and other aspects. At the same time, its advantages are emphasized by its convenience and vast application areas. The reliability and efficiency of the connection can be improved through the reasonable selection and correct use of closed-end rivet nuts.
