If the stainless steel nut is locked, find out the locking reason first

Locking occurs when purchasing stainless steel nuts. In fact, this is a very normal situation. The more common reason is that the raw material of stainless steel itself or improper use.

Nut material causes locking

Due to the essential difference between stainless steel and carbon steel materials, stainless steel fasteners are relatively soft, carbon steel fasteners are relatively hard, stainless steel has very good ductility, but its hardness is compared with carbon steel. There are still some differences. The locking problem often occurs on the fastening parts of stainless steel materials, aluminum alloy materials and titanium alloy materials. The above metal alloy materials have anti-corrosion properties themselves. A relatively thin layer of oxide material is produced on the metal surface to avoid further deterioration of corrosion.

When the stainless steel nut is locked, the pressure and heat between the teeth will destroy and remove the chromium oxide layered substances, which will cause the metal raw teeth to be directly plugged or sheared, resulting in stickiness. In the case of sticking, when the sticking objects appear continuously, the stainless steel fasteners will be completely locked and locked in the future, resulting in no way to remove or lock them.

Improper use leads to lockup

Locking is unavoidable due to the raw material problem of stainless steel nut, but it can be completely avoided during use. The main reason for locking is that the tooth pattern is relatively rough or some foreign objects are pasted. If there are solder joints or other metal chips clipping In the tooth pattern, it will lead to locking.
