Rivet nuts come in a variety of shapes and sizes, with options to suit different applications:
- Body styles: Round, hex, square.
Round bodies are the most common, especially knurled ones due to their resistance to spinning;
Hexagonal bodies provide the best resistance to over-torque turning when used in hexagonal holes.
- Head styles: Flat head, countersunk head, large flange, small flange, wedge head.
Large flanges reinforce the hole and prevent push-out;
Countersunk/low-profile heads provide a flush finish;
Wedge heads prevent turning in soft materials.
- End styles: Open end, closed end.
Closed end rivet nuts seal the threads, making them ideal for applications where water or dirt ingress is a
concern;
- Materials: Steel, stainless steel, aluminum, brass.
Aluminum rivet nuts offer decreased weight, corrosion resistance, and high electrical and thermal conductivity;
The choice of material depends on the strength and corrosion resistance requirements.
