Metal Stainless Steel Nut
Metal Stainless Steel Nut

Metal locknut is a nut that can self-lock by friction. In order to prevent this phenomenon, self-locking nuts were invented because of vibration and other reasons that the ordinary nuts would loosen themselves during use. Self - locking nut its main function is anti - loose, anti - vibration. For special occasions. Its working principle is generally self-locking by friction. The type of self-locking nut according to the function classification has the inlaying nylon ring, the neck closure, and the metal anti-loose device. They all belong to effective torque type locknuts.

Self-locking nuts generally rely on friction, the principle of which is pressed into the preset hole of sheet metal through embossing teeth, the general square preset hole aperture is slightly smaller than the pressure rivet nut. The nut is connected with the locking mechanism. When the nut is tightened, the locking mechanism locks the ruler body, and the ruler frame cannot move freely to achieve the purpose of locking. When the nut is loosened, the locking mechanism disengages the ruler body and the ruler frame moves along the ruler body.
