Cage Clip Nut

The Yellow Zinc Plated Spring Cage Clip Nut is a pre-installed captive fastener specially designed for metal rack profiles and thin sheet metal enclosures, effectively solving the problem of loose and lost nuts during equipment assembly and maintenance. It consists of a central threaded nut insert and an integrated U-shaped elastic spring clip frame, which can be snapped into square or rectangular mounting slots to stay fixed without falling off.

Manufactured from high ductility low carbon spring steel for the clip and standard carbon steel for the nut core, this clip nut delivers stable elastic clamping force and reliable thread bearing capacity. The whole piece undergoes color yellow zinc electroplating treatment, forming a dense multi-color anti-corrosion zinc layer that blocks moisture and oxidation, providing excellent rust protection for indoor electrical and communication equipment operating environments.

The unique U-shaped spring clip structure provides consistent elastic holding force. After being clipped into equipment frame slots, the bent spring arms tightly clamp the profile wall to prevent sliding or dropping during bolt installation. The nut insert has a small floating range inside the clip frame, allowing slight position adjustment to align misaligned bolt holes and greatly improving assembly efficiency. Precisely tapped internal threads match standard metric bolts perfectly, supporting repeated disassembly for equipment overhaul and component replacement.

U type spring clip nuts are widely applied to server rack frame assembly, network switch cabinet fixing, electrical control box sheet metal connection, precision instrument chassis mounting, communication equipment shell fastening and automotive thin plate interior assembly. Its pre-mounted captive design eliminates tedious nut retrieval work on production lines and reduces assembly error rates.

We provide full OEM and ODM custom manufacturing services and support tailor-made production based on customer technical drawings, physical samples and special dimensional requirements. Custom thread sizes, spring clip thickness, overall outer dimensions and personalized export packaging schemes are available to meet diverse electrical and communication engineering project demands. Private laser marking and custom brand printing services are also supported for cabinet hardware distributors, network equipment manufacturers and electrical engineering contractors.

Each Yellow Zinc Plated Spring Cage Clip Nut is produced under strict electronic fastener quality control standards. All finished clip nuts pass comprehensive dimensional inspection, thread precision test, spring clamping elasticity sampling test and surface yellow zinc coating uniformity check before shipment, to guarantee accurate thread tolerance, stable long-lasting spring holding force and uniform anti-corrosion plating for every production batch.
