Clips, hangers, and hooks are essential mechanical components used for fastening, suspending, or securing objects in various industrial and commercial applications. These devices enable efficient load distribution, space optimization, and structural stability. Their importance spans across industries such as automotive, aerospace, construction, and logistics, where reliability and safety are critical.
| Type | Functional Features | Application Examples |
|---|---|---|
| C-Clips | Internal/external retaining rings with radial locking | Shaft assemblies in automotive gearboxes |
| Spring Clips | Elastically deformable for quick fastening | Aircraft interior panel fasteners |
| U-Hangers | Adjustable height suspension with threaded rods | Commercial HVAC duct support systems |
| Toggle Hooks | Spring-loaded pivoting mechanism | Temporary equipment suspension in construction |
| Self-Locking Hooks | Automatic locking at specific load thresholds | Cargo securement in container shipping |
Typical designs include:
| Parameter | Significance | Typical Range |
|---|---|---|
| Working Load Limit (WLL) | Determines safe operational capacity | 50N - 50kN |
| Material Hardness | Affects wear resistance and fatigue life | 45-60 HRC (steel components) |
| Corrosion Resistance | Measured by salt spray test duration | 24-1000 hours |
| Temperature Range | Operating environment compatibility | -40 C to +250 C |
| Dimensional Tolerance | Ensures interchangeability | 0.05mm to 0.5mm |
| Manufacturer | Key Products | Technical Highlights |
|---|---|---|
| Eaton | Hi-Spec aerospace clips | AS9100 certified, 1250MPa tensile strength |
| 3M | Command adhesive hooks | Microsphere adhesive technology, 5kg capacity |
| ITW | Grade 8 bolt hangers | Zinc-nickel plated, M10-M20 thread sizes |
