Hex Rivet Nuts, pull caps, instant pull caps are used in the fastening fields of various metal plates, pipes and other manufacturing industries. They are widely used in automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, decorations, etc., as well as the assembly of light industrial products. The purpose of developing this product is to solve the shortcomings of welded nuts for thin metal plates and thin tubes, such as relatively easy to melt, easy to weld basic materials, easy to slip in internal threads and other shortcomings. It does not require tapping internal threads, does not require welding nuts, and is efficient and easy to use.
Types of rivet nuts
Hexagon head half hex rivet nuts with through hole, blind hole, knurled and non-knurled.
The use of rivet nuts
If the nut of the product needs to be installed externally and the internal space is small, the pressure head of the sub-rivet machine cannot be used for pressure riveting, and methods such as sprouting cannot meet the strength requirements, pressure riveting and expansion riveting are not feasible of. Blind riveting must be used. It is suitable for the fastening field of plates and tubes (0.5MM-6MM) of various thickness. It can be riveted with a pneumatic or manual rivet gun at one time, which is convenient and firm; instead of the traditional welding nut, it can make up for the shortcomings of thin metal plates, thin tubes easy to weld and the welding nuts are not smooth.
Rivet nuts are mainly used for non-structural bearing bolt connections, such as the connection of internal parts such as railway passenger cars, road passenger cars and ships. The improved rivet nut that prevents rotation is better than the fixed nut on the airplane. Its advantages are lighter weight, no need to fix the pallet nut with rivets in advance, and the back of the base plate can still be used without operating space.
The specifications of rivet nuts in the national standard are M3, M4, M5, M6, M8, M10 and M12. In fact, it is recommended to use M6 and M8, because it is possible to tap directly on the base metal. If the thread is larger, the weight of the bolt will increase greatly. The increase in connection strength is limited, that is, unreasonable matching.
