Clip Nut

The Yellow Zinc Plated U Type Spring Clip Nut is a pre-mounted captive fastener designed for slotted metal rack profiles and thin sheet metal housings, effectively solving the problem of lost loose nuts during production assembly and equipment maintenance. It consists of a stamped U-shaped elastic spring clip and a firmly welded hex nut on the base plate, which can be slid directly into equipment frame slots and locked in place without falling off.

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

The folded U-shaped elastic side arms maintain constant clamping tension after being inserted into rack slots, tightly gripping the metal plate wall to prevent sliding and dropping during bolt tightening operations. The hex nut is fixed rigidly to the clip base without floating displacement, ensuring precise thread alignment with matching bolts and reducing assembly adjustment time. Precisely tapped internal threads fit standard metric bolts perfectly, supporting repeated disassembly for component replacement and equipment overhaul.

U type spring clip nuts are widely used for server rack frame assembly, network switch cabinet fixing, electrical control box sheet metal connection, precision instrument chassis mounting, automotive interior thin panel assembly and solar bracket installation. Its slide-in pre-install design greatly boosts production line assembly efficiency and eliminates nut loss troubles 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 steel 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.
