Cage Nut With Float
Products Description
The Cage Nut with Float is a fastening component that integrates an elastic floating mechanism.
Unlike traditional welding nuts or fixed-pressure rivet nuts, its internal nut can achieve a certain range of floating displacement inside the cage, thereby automatically compensating for hole position deviations during installation.
Its main components include:
floating nut body
Elastic retention structure
metal cage
Anti-falling positioning mechanism
When the bolt is installed, the nut can automatically adjust its position to help the threads align quickly, significantly improving assembly efficiency and installation success rate.
Core Functions and Application Advantages: Unaffected by High-Frequency Vibration and Blind Hole Limitations
Cloud Computing Centers and Standard IT Racks (19-inch Racks)
In the installation of large-scale servers, switches, and power distribution PDUs, Floating Nut Assemblies can be pre-positioned in the square holes of vertical columns. It perfectly accommodates the slight dimensional differences in server rails from different manufacturers, enabling modular, rapid, and stable rack mounting.
Mobile Communication Base Stations and Outdoor Enclosures
Outdoor base stations face wind-borne vibrations year-round. The floating device effectively absorbs high-frequency, low-amplitude vibrations, preventing structural loosening of bolts during long-term operation and ensuring the mechanical stability of the base station signal.
Rail Transit and Rolling Stock Control Boxes
In control boxes inside high-speed rail and subway chassis or carriages, where the vehicle operation involves significant shock and vibration, our high-grade Cage Nut Assembly maintains consistent clamping force under harsh mechanical conditions.
Manufacturing Process: Precision Refinement of Micron-Level Stamping and Elastic Shaping
| Precision Multi-Station Progressive Stamping | The cage frame utilizes a high-precision, high-speed stamping press and customized progressive dies, sequentially completing flattening, trimming, bending, forming, and cutting in more than 15 stations. Die clearances are controlled at the micron level, ensuring a smooth, burr-free cut surface and consistent bending radii-the cornerstone of elastic stability. |
| Square Nut Cold Forging and Tapping | A multi-station cold forging machine is used, allowing metal fibers to smoothly recombine within the die, resulting in Floating Nut Combos with extremely high density and tensile strength. Subsequent chip-free tapping using precision taps ensures accurate thread profiles and reduces bolt tightening torque fluctuations. |
| Heat Treatment and Elastic Shaping | This is the core process that determines the product's success or failure. The stamped cage frame and the cold-forged nut separately enter a mesh belt heat treatment furnace. The cage frame achieves excellent elasticity through quenching and medium-temperature tempering (spring steel hardenability control); the U-Nut Floating Assembly achieves a balance of strength and toughness through tempering. Strict atmosphere protection and full hardness inspection prevent any defective product with weak elasticity or brittle threads from leaving the factory. |
| Automated pre-assembly and surface treatment | The Clip-On Floating Nut and cage frame are pre-fitted on a fully automated production line, and then the entire assembly enters the electroplating line (e.g., environmentally friendly blue-white zinc, black zinc, mechanical galvanizing, etc.). After electroplating, high-speed centrifugal drying and low-temperature baking ensure no crystalline salt residue remains inside the threads, guaranteeing smooth screwing. |
