Flare-In Nuts VS Self Clinching Nuts

Flare-in nuts are a kind of fasteners used in sheet metal, sheet metal, chassis, and cabinets. Flare-in nuts have two shapes: one is hexagonal, which is indicated by NZ NZS; the other is cylindrical, which is represented by Z ZS shows. The ones that are pressed into the plate are all round and have no inner teeth. Usually the plate hole is pre-opened on the thin plate, the rivet nut is put into the plate hole, the part without internal teeth is expanded from the inside to the outside with a jig, and then the rivet nut is tightly riveted with the thin plate. Riveting nuts are generally not hardened, so as to ensure their toughness. When rising with a jig, the components can be riveted tightly without cracking the components. Therefore, when producing, it is very important to choose good raw materials. Make the rivet nut fasten on the thin plate, and then form an effective fixed internal thread on the thin plate.

Rivet nuts can be divided into two types: fast-cutting steel rivet nuts Z NZ type and Stainless Steel Rivet Nuts ZSNZS type in terms of raw materials; from the shape, they can be divided into cylindrical rivet nuts Z ZS; hexagonal rivet nuts NZ NZS four types, Applied to different application environments respectively.

There is no specific national standard for rising rivet nuts. The early manufacturers came from the United States, and after being introduced into China, they gradually formed today's industry standards. Most of the domestic producers come from Shenzhen and other regions in Guangdong.

Self clinching nuts are a kind of nuts applied to thin plates or sheet metals. They are round in shape and have embossed teeth and guide grooves at one end. The principle is to press the embossing teeth into the preset holes of the sheet metal. Usually, the diameter of the square preset holes is slightly smaller than the embossing teeth of the rivet nut. After pressure, the flower teeth of the rivet nut are squeezed into the plate so that The periphery of the hole is plastically deformed, and the deformation is squeezed into the guide groove, and then the locking effect occurs.

Rivet nuts are divided into S-type fast-cutting steel rivet nuts, CLS-type Stainless Steel Rivet Nuts, SP-type stainless steel rivet nuts, and CLA-type copper and aluminum rivet nuts, respectively, for different application environments. environment. The standard range is usually from M2 to M12.

There is no consistent national standard for rivet nuts. The earliest rivet nuts came from manufacturers in the United States. After being introduced in China, they gradually formed the current industry standard and were accepted by the chassis, cabinet and sheet metal industries.
