Stainless steel rivet nuts have gradually replaced the traditional welding nuts with the advantages of non rusting, light weight, etc. Now we all like to use stainless steel rivet nuts, but we need to pay attention to some things in the use process.

The basic use of stainless steel rivet nuts is the same as that of carbon steel rivet nuts. However, it is mainly used in the connection of non structural load-bearing bolts, such as the connection of rail cars, road buses, ships and other interior trim parts. The improved rivet nut that can prevent spinning is more excellent than the aircraft bracket nut. Its advantages are that the weight is lighter, the bracket nut does not need to be fixed with rivets in advance, and the back of the base material can still be used without operating space.

Precautions for stainless steel rivet nuts:

If the stainless steel rivet nut is tightened too tightly, the interface will be rusted, which is not conducive to disassembly. It is recommended to tighten the nut by hand first, and then use a wrench to tighten the nut for half a turn to one turn. When installing the automobile tire, the screws shall not be tightened too tightly, otherwise the screws may be deformed and the fixing effect may be affected. On the same tire, the tightness of each screw should be even, and no individual screw should be tightened very tightly, otherwise the driving of the tire will be affected, and the screw may be broken due to uneven stress in severe cases.

If stainless steel rivet nuts need to be installed outside, but the space inside is too small to allow the pressure head of the riveter to enter for riveting and sprouting and other methods cannot meet the strength requirements, then both riveting and expanding are not feasible.

Stainless steel rivet nuts can be riveted on a single sheet, or two sheets can be riveted together. They are both rivets and nuts; It is also applicable to closed workpieces that can only be operated on one side. In addition, for light metal workpieces requiring threaded connection, stainless steel rivet nuts are compact and easy to use inserts.

As the stainless steel rivet nut is deformed under the axial pressure applied at its two ends, the stress is better than the bulge forming of simple parts or tubes under radial pressure. After riveting, the length of stainless steel rivet nut will be shortened, and its shrinkage is related to its material plasticity and size. In order to prevent the bulge coefficient from exceeding the allowable value and causing cracks in bulge forming, its shrinkage must be controlled.
