There are many fasteners that we can see around us, and stainless steel rivet nut is also a kind of fastener. Fasteners include bolts, studs, screws, nuts, washers, and pins.
Locking or seizure often occurs on fasteners made of stainless steel, aluminum alloy, and titanium alloy materials. These metal alloys have anti-corrosion properties. When the surface is damaged, a thin oxide layer is formed on the metal surface to prevent further corrosion. When the stainless steel fasteners are locked, the pressure and heat generated between the teeth will destroy this oxide layer, causing blockage or shearing between the metal threads, and then adhesion. When this phenomenon continues to occur, the stainless steel fasteners will be completely locked and can no longer be removed or continued to be locked. Usually, this series of blocking, cutting, sticking, and locking actions occur in just a few seconds, so a correct understanding of the use of such fasteners can prevent this phenomenon.
And rivet nut aluminium also needs to pay more attention to prevent this phenomenon from happening. www.khfastener.com
