Introduction And Differences Between Floating Nut Inserts And Retaining Nuts

Apr 07, 2026 Leave a message

A Floating Nut Insert is a special type of threaded fastener, typically composed of an internal hexagonal nut, an external conical surface, and a flexible washer. It can move freely axially without affecting the transmission of tightening force, can withstand high-intensity vibration and thermal expansion deformation, and prevents the fastener from locking or loosening. It is widely used in the automotive, aerospace, and machinery industries.

 

Floating Nut Clips automatically adjust their position when the fastener becomes loose or the tightening force decreases, ensuring a uniform distribution of tightening force, enhancing the vibration resistance and safety of the fastener. They also provide a buffer layer between fasteners of different materials or roughness, preventing corrosion and oxidation, and extending service life. Their use also effectively shortens installation time and reduces installation costs.

Unlike Cage Nut with Floats, cage nuts are another commonly used fastener, and the two differ significantly in structure and application. Their main feature is that through an internal slot structure, they can be easily fixed into holes in plates or pipes without welding or screws. Installation and disassembly are very convenient, and their main applications include machinery, automation equipment, and rail transportation equipment.

 

The core advantage of Spring-Steel Floating Nuts lies in their special internal structure, which allows for a degree of free floating. Even under vibration or uneven stress, they maintain a good fastening effect and effectively prevent loosening. Therefore, they are commonly used in fields requiring high fastening stability, such as automobiles, motorcycles, and aerospace equipment.

Besides differences in application scenarios and core characteristics, retaining nuts and Cage Nut with Floats also differ in structure, materials, and installation methods. A retaining nut's structure mainly consists of a threaded portion and a retaining groove, while the latter's structure mainly consists of a threaded portion and a floating portion.

 

In terms of materials, retaining nuts are generally made of carbon steel or stainless steel, while Float-Nut Cage Units are often made of copper or stainless steel.

 

Regarding installation methods, retaining nuts are mainly fixed to holes in plates or pipes via retaining grooves, while Cage-Type Floating Nuts are mainly fixed to the components requiring fastening via threads.

 

In summary, Floating Cage Nuts and retaining nuts are two types of fasteners with different functions. They differ in structure, materials, installation methods, and application scenarios. In practical use, it is necessary to select the appropriate fastener based on specific needs and application scenarios to ensure fastening effectiveness and safety.
