Flat-head Hexagonal Blind Rivet Nut

The flat-head hexagonal blind rivet nut is another common type of blind rivet nut. The following is a detailed introduction to the flat-head hexagonal blind rivet nut:

Definition and Structure of the Flat-head Hexagonal Blind Rivet Nut

The flat-head hexagonal blind rivet nut is a tubular nut with internal threads. One end is flat, and the other end has a flange or a bell mouth for riveting. Its most prominent feature is that the head of the nut is hexagonal, similar to a common hexagonal nut. This design makes it convenient to use tools such as wrenches for installation and disassembly.

There are usually various forms of grooves or teeth on the cylinder to increase the friction force and anti-loosening performance after riveting. The internal threads are used to cooperate with bolts or screws to achieve the connection between components.

Features of the Flat-head Hexagonal Blind Rivet Nut

High Connection Strength: Connected to the thin plate by riveting, it can provide reliable fastening force, and can withstand large tensile force and shear force. It is suitable for connection parts that need to bear a certain load.

Convenient Installation: Just use simple riveting tools to rivet the blind rivet nut onto the thin plate. There is no need to carry out complex thread processing on the thin plate. The installation process is simple and efficient, which can effectively improve work efficiency.

Easy to Operate: The hexagonal head design allows the use of conventional tools such as hexagonal wrenches during the installation and disassembly process. It is convenient to apply force and easy to control the tightening torque to ensure the firmness of the connection.

Manufacturing Standards of the Flat-head Hexagonal Blind Rivet Nut

Common national standards include relevant blind rivet nut standards that regulate its dimensions, tolerances, materials, mechanical properties, and surface treatments. For example, the parts in standards such as GB/T 17880.1 - 1999 that involve the flat-head hexagonal blind rivet nut clarify the dimensional parameters such as the outer diameter, inner diameter, height, and hexagonal head size of blind rivet nuts of different specifications, as well as the mechanical property requirements such as the tensile strength and hardness of the materials.

Materials and Surface Treatments of the Flat-head Hexagonal Blind Rivet Nut

Commonly Used Materials: Generally, materials such as low-carbon steel, stainless steel, and aluminum alloy are used. The flat-head hexagonal blind rivet nuts made of low-carbon steel have high strength and toughness and relatively low cost; those made of stainless steel have good corrosion resistance and are suitable for humid environments or environments with corrosive media; the blind rivet nuts made of aluminum alloy are light in weight and are often used in occasions with requirements for weight, such as in the aerospace, electronic device, and other fields.

Surface Treatments: In order to improve the corrosion resistance and wear resistance of the flat-head hexagonal blind rivet nuts, surface treatments are usually carried out. Common treatment methods include galvanizing, nickel plating, chrome plating, etc., which can form a protective film on the surface of the nut to prevent oxidation and corrosion. In addition, according to special requirements, blackening treatment, phosphating treatment, etc. may also be adopted.

Application Fields of the Flat-head Hexagonal Blind Rivet Nut

Machinery Manufacturing: In the manufacturing of various mechanical equipment, it is used to connect thin plate structural parts, such as equipment casings, protective covers, etc. It can not only ensure the connection strength but also facilitate later maintenance and disassembly.

Automobile Manufacturing: It is often used for the connection of parts such as automobile bodies and frames, such as the connection of body side panels and chassis components. It can withstand various stresses during the driving process of the automobile and is convenient to operate during the production and maintenance of the automobile.

Electrical Equipment: In electrical control cabinets, distribution boxes and other equipment, it is used to fix thin plate-shaped electrical component mounting plates, panels, etc., which is convenient for installation and maintenance and ensures the reliability of the connection.

Construction Industry: It can be used for the connection of thin plates in building steel structures, such as the connection of light steel structure roof panels and wall panels, as well as the installation of some building decoration components, providing a firm connection and being convenient for construction operations.

Marking Method of the Flat-head Hexagonal Blind Rivet Nut

The marking content includes information such as the product name, nominal diameter, nominal length, material, and surface treatment. For example, the marking "Blind Rivet Nut GB/T 17880.1 M6×10 - 10B Zn" indicates a flat-head hexagonal blind rivet nut with a nominal diameter of 6mm, a nominal length of 10mm, a material of 10B steel, and a surface treatment of galvanizing.

Purchase Precautions for the Flat-head Hexagonal Blind Rivet Nut

Size Matching: According to the actual thickness of the thin plate used and the connection requirements, precisely select a flat-head hexagonal blind rivet nut of an appropriate specification to ensure that its outer diameter, inner diameter, length, and hexagonal head size match the installation part to ensure the riveting effect and connection strength.

Material Selection: Select a blind rivet nut of an appropriate material according to the usage environment and working conditions. For example, in a humid or corrosive environment, a stainless steel blind rivet nut or a blind rivet nut with special anti-corrosion treatment should be selected; for parts that bear a large load, the strength and toughness of the material need to be considered.

Quality Inspection: When purchasing, carefully check the appearance quality of the blind rivet nut, which should have no defects such as cracks, burrs, and deformations. At the same time, pay attention to checking the accuracy and smoothness of its threads to ensure good cooperation with bolts or screws and guarantee the reliability of the connection.

Installation and Maintenance of the Flat-head Hexagonal Blind Rivet Nut

Installation: When installing the flat-head hexagonal blind rivet nut, first process a suitable installation hole on the thin plate, then put the blind rivet nut into the hole, and use special riveting tools (such as pneumatic rivet guns, hydraulic riveting machines, etc.) to rivet the blind rivet nut. During the riveting process, control the pressure and stroke of the riveting tool well to make the flange or bell mouth of the blind rivet nut fully deformed and closely combined with the thin plate.

Maintenance: Regularly check the connection condition of the blind rivet nut to see if there are problems such as looseness, deformation, or corrosion. If the blind rivet nut is found to be damaged or the connection is not firm, it should be replaced in a timely manner. When repairing or maintaining the equipment or product, also pay attention to checking and maintaining the blind rivet nut to ensure the reliability of the entire connection system.
