Rivet nut
The rivet nut is a kind of fastener used in sheet metal, sheet, chassis and cabinet. The rivet nut has two shapes: a hexagonal shape, represented by NZ NZS; the other is cylindrical, represented by Z ZS . The pressure plate is round and has no internal teeth. Generally, the plate hole is pre-opened on the thin plate, and the rivet nut is placed in the hole of the plate, and the inner portion is raised from the inside to the outside with the jig, so that the rivet nut and the thin plate are tightly riveted. The rivet nut is generally not hardened to ensure its toughness. When the fixture is raised, the component can be tightened and the component is not cracked. Therefore, when producing, it is important to choose a good material. The riveted nut is riveted to the sheet to form an effective fixed internal thread on the sheet. The rivet nut is divided into two types: fast-cut steel rivet nut Z NZ type and stainless steel rivet nut ZSNZS type; from the shape, it is divided into cylindrical rivet nut Z ZS; hexagonal rivet nut NZ NZS four kinds, They are applied to different usage environments. Material is iron-galvanized Stainless steel Model Z ZS M3 M4 M5 M6 M8 M10 M12 can be determined according to the customer's thickness. Round rivet nuts and hexagonal rivet nuts are widely used in the inlaying process of metal slabs, control boxes and power cabinets. The special structure of the structure, when assembling, only need to put the rivet nut into the hole of the metal plate, and realize the operation of "up and riveting", which has the following advantages: 1. Due to the special toughness of the steel, the special treatment is adopted. It rises from the inside to the outside, so that the tightening rivet nut is tightly tightened in the hole of the plate, the components are assembled firmly, it is not easy to fall off, and the assembly process is simple. 2, in order to further ensure that the rivet nut does not slip, many manufacturers use the method of increasing the teeth; 3, the raw materials are easy-cutting iron or free-cutting stainless steel; the rivet nut code is detailed:
Example: Z - M3 – 1.2
Round iron material rivet nut thread code Applicable plate thickness 1.2
ZS – M4 – 2
Round stainless steel rivet nut Thread code Applicable plate thickness 2
NZ - M3 – 1.5
Hexagonal iron material rivet nut Thread code Applicable plate thickness 1.5
NZS – M8 – 5
Hexagonal stainless steel rivet nut Thread code Applicable plate thickness 5
