Countersunk head rivet nuts (also known as flat head rivet nuts) are internally threaded fasteners designed specifically for sheet metal. Installation is quick and easy, requiring only a rivet gun. The operation is silent and highly efficient. Simply place the rivet nut into the muzzle of the rivet gun, insert the end of the rivet nut into the sheet metal hole, and tighten the gun to complete the riveting.
There are many types of flat head rivet nuts, including commonly used flat head cylindrical rivet nuts, flat head hexagonal rivet nuts, and flat head striped rivet nuts. Other options include countersunk head striped rivet nuts, countersunk hexagonal rivet nuts, small countersunk head rivet nuts, and countersunk imperial rivet nuts.
Rivet nuts are classified into internal and external hexagonal rivet nuts, semi-hexagonal rivet nuts, countersunk head rivet nuts, small countersunk head rivet nuts, flat head rivet nuts, blind hole rivet nuts, and elevator-specific rivet nuts. They are made of carbon steel and stainless steel.
This type of rivet nut is suitable for aluminum alloy substrates of varying thicknesses and steel plates with thicknesses ranging from 1 to 2.5 mm. The use of steel rivet nuts in aluminum alloy components is particularly noteworthy, simplifying the tedious process of pre-embedded steel plates and significantly improving processability.
