Clip Nut

The Yellow Zinc Plated U Type Spring Clip Nut is a pre-installed captive fastener designed for metal rack slots and thin sheet metal enclosures, solving the trouble of lost loose nuts during assembly and equipment maintenance. It consists of a stamped U-shaped elastic spring clip and a fixed hex nut welded on the base plate, which can be directly slid and clipped into equipment frame grooves for fixed positioning without falling off.

Manufactured from ductile low carbon spring steel for the clip and standard Grade 4.8 carbon steel for the hex nut, this clip nut delivers stable elastic clamping force and reliable load-bearing thread performance. The entire assembly undergoes color yellow zinc electroplating, forming a multi-layer colorful anti-corrosion zinc coating that isolates air and moisture to resist rust, suitable for long-term indoor electrical, communication and light outdoor equipment working environments.

The integrated U-shaped spring clip features folded elastic edges that generate constant clamping tension after being inserted into rack slots, locking the nut firmly in place to prevent sliding and dropping during bolt tightening. The hex nut is fixed to the clip base without floating displacement, ensuring precise thread alignment with matching bolts to reduce assembly adjustment time. Precision tapped internal threads fit standard metric bolts seamlessly, supporting repeated disassembly for component replacement and equipment overhaul.

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, automotive interior thin plate assembly and solar bracket installation. Its slide-in pre-install design greatly improves production line assembly efficiency and avoids nut loss during on-site maintenance.

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, clip width/length, spring thickness, plating thickness and personalized export packaging options are available to meet diverse electrical, solar and communication engineering project demands. Private laser marking and custom brand printing services are also supported for cabinet hardware distributors, network equipment manufacturers and solar engineering contractors.

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