What material and thickness are the rivet nuts suitable for?

What material and thickness are generally suitable for rivet nuts? Let's learn more about Hongrui Hardware together~

Expansion rivet nut (also known as expansion nut or pull rivet nut) is a fastener commonly used on metal plates, especially suitable for situations where it cannot be contacted from the back. Their design enables fastening in single-sided operation, making them widely used in industries such as automotive, aerospace, and home appliance manufacturing. The expansion rivet nut is suitable for various types of materials and thicknesses, and the specific application scope is as follows:

Applicable materials

Metal sheet: Rivet nuts are commonly used for metal sheets such as steel, aluminum, copper, etc. These materials are typically used to manufacture chassis, electrical enclosures, and other devices that require fasteners.

Composite materials: Certain types of rivet nuts can also be used for composite material sheets, such as glass fiber reinforced plastic (FRP) or carbon fiber reinforced plastic (CFRP), which are very popular in the aerospace and automotive industries due to their non-conductive and lightweight properties.

Plastic sheet: For some harder engineering plastics such as polycarbonate (PC), ABS, etc., specialized rivet nuts can also be used.

Applicable thickness range

The choice of rivet nut not only depends on the material of the board, but also on the thickness of the board. Each type of rivet nut has its own range of sheet thickness for use. Generally speaking:

For thinner sheets (usually 0.5mm to 2.5mm), standard rivet nuts can be selected.

For medium thickness plates (2.5mm to 4.0mm), nuts with greater expansion capacity need to be selected.

For thicker plates (over 4.0mm), special designed rivet nuts may be required, or other types of fasteners may be considered.

Specific selection guide

Material hardness: For materials with high hardness, high shear strength rivet nuts should be selected; For softer materials, ordinary rivet nuts can be chosen.

Load demand: If it is expected to bear a large load, then a rivet nut with higher load-bearing capacity should be selected.

Environmental factors: Components working in corrosive environments should choose rivet nuts made of materials with anti-corrosion capabilities, such as stainless steel or coated nuts.

Temperature range: For components working under poor temperature conditions, the thermal stability of the material and the matching of the thermal expansion coefficient between the nut and the plate should be considered.

In short, when choosing a suitable rivet nut, it is necessary to comprehensively consider factors such as the material type, thickness, load requirements, and usage environment of the board. The correct selection can ensure the reliability and service life of fasteners, thereby avoiding failures or accidents caused by fastener failure. In practical applications, it is recommended to refer to specific product manuals or consult professional suppliers for advice.
