What is a self-locking floating anchor nut double ear?

The self locking floating anchor nuts double lug mounting is a special fastener, mainly used in application scenarios that require high strength and vibration resistance. The following is a detailed introduction to the self locking floating anchor nuts double lug mounting:

1. Definition and function

The self locking floating anchor nuts double lug mounting is a nut that can self-lock by friction, mainly used to prevent loosening caused by vibration. Its functions mainly include anti-loosening and anti-vibration, and it is suitable for various mechanical and electrical products, especially in environments with a temperature range of -50℃ to 100℃.

2. Working principle

The working principle of the self locking floating anchor nuts double lug mounting is mainly based on friction. The embossed teeth are pressed into the preset hole of the sheet metal. The aperture of the preset hole is slightly smaller than the rivet nut. When the nut is tightened, the locking mechanism will lock the ruler body to prevent the ruler frame from moving freely, thereby achieving 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.

3. Application scenarios

The double ears of self-locking floating anchor nuts are widely used in various occasions that require high strength and vibration resistance, such as aerospace, aviation, tanks, mining machinery, automobile transportation machinery, agricultural machinery, textile machinery, electrical products, etc. Due to its excellent anti-vibration and anti-loosening performance and several or even dozens of times higher vibration life, it is in great demand in these fields.

4. Specifications and standards

The double ears of self-locking floating anchor nuts have various specifications, and the common ones are different specifications such as M3 to M16. Its standards include the double-ear sealed floating self-locking nut specified in GJB125.1~125.6-86, which consists of four parts: sealing cover, self-locking nut, pressure ring, and sealing ring. It is suitable for working pressure not more than 2atm and working medium is gasoline, kerosene, water or air.
