1. Our Main Spring Clip Product Line
1.1 Stainless Steel U Clips – Rivet-Free Panel Fasteners
Eliminate loose screws and abnormal rattling. SUS301/SUS304 U clips lock firmly into round & square holes, supporting tool‑free assembly for electrical cabinets, auto parts and home appliances. The spring‑back design offsets vibration and thermal expansion for long‑term stable clamping.
| Parameter | Custom Options |
|---|---|
| Materials | SUS301, SUS304, Beryllium Copper, Phosphor Bronze |
| Thickness | 0.08 mm – 3.0 mm |
| Surface Finish | Polished, Nickel Plating, Gold Plating, Black Electrophoresis |
| Applications | Panel fasteners, wire harness clips, cabinet retainers |
1.2 Mini Spring Clips & Small Precision Clips
Perfect for compact equipment including medical sensors, portable electronics and miniature switches. Burr‑free stamping achieves tight ±0.02 mm tolerances. Non‑magnetic phosphor bronze versions support MRI medical devices.
Minimum width: 1.5 mm
Minimum thickness: 0.08 mm
Magnetic permeability: < 1.0 µ
1.3 Spring Battery Connectors & Battery Spring Plates
Custom lithium battery contacts for power banks and battery packs. Gold‑plated contact areas lower resistance and resist oxidation, with over 50,000 compression service life. We tailor bending shapes to match your battery housing drawings.
Optimized arc design to avoid fatigue fracture
Plating options: gold, nickel, silver, tin
1.4 Spring Steel Retaining Clips – Anti-Vibration Locking
65Mn/SK5 heat‑treated spring steel clips for machinery, automotive chassis and industrial equipment. Serrated edges strengthen grip on smooth shafts to prevent loosening.
Typical uses: gear retention, shaft locking, cable fixing clips.
Besides standard retaining clips, we also customize pipe spring clips, spring safety clips and spring wire clips based on your drawings and samples for cable bundling and equipment safety protection.
