Different Types of Rivet Nuts

Rivet nuts, also known as blind rivet nuts or threaded inserts, are widely used fastening solutions that provide strong, reliable threads in thin or soft materials. They can be installed from one side of the workpiece, making them ideal for applications where access is limited. To better understand their versatility, rivet nuts can be classified according to their head shape, body shape, and installation method.

Classification by Head Shape

Head shape determines how the rivet nut sits on the surface of the material and affects both appearance and load-bearing performance.

• Flat Head Rivet Nut – The most common type, offering a large bearing surface for stable fastening.
• Countersunk Head Rivet Nut – Designed to sit flush with the surface, ensuring a neat finish without protrusion.
• Reduced/Small Head Rivet Nut – Suitable for compact installation spaces or applications where appearance matters.

Classification by Body Shape

The body design of a rivet nut influences its resistance to rotation and its performance in different materials.

• Round Body Rivet Nut – Standard type for thin sheet metal and tubular materials.
• Knurled Body Rivet Nut – Features knurled or ribbed surfaces that prevent spinning during tightening.
• Hex Body Rivet Nut – Provides superior anti-rotation performance, especially effective in softer base materials.
• Open-End Rivet Nut – Allows the use of bolts of various lengths since the threaded hole remains open.
• Closed-End Rivet Nut – Sealed at the end to prevent water, dust, and contaminants from entering, making it ideal for automotive, marine, and electronics applications.

Classification by Installation Method

Different installation methods make rivet nuts suitable for both small-batch use and large-scale production.

• Manual Installation – Using hand rivet nut tools, this method is convenient for maintenance or low-volume assembly.
• Pneumatic/Hydraulic Installation – Offers high efficiency, stable performance, and is widely used in mass production lines.
