Product Description
Washers are essential fasteners used between the supporting surface of bolts, screws or nuts and connected parts. They protect surfaces, prevent loosening, and serve various special purposes. Washer types include:
- Flat washers (Class A, C, chamfered type)
- High strength washers for steel structures
- Spherical and conical washers
- I-steel and channel steel square inclined washers
- Standard, light, and heavy spring washers
- Internal/external tooth lock washers
- Single/double ear stop washers
- Round nut stop washers
Key Features
- Flat Washers: Increase contact area, disperse pressure, prevent crushing of soft materials
- Spring Washers: Provide tension to increase friction between nut and bolt (Material: 65Mn spring steel, HRC44-51 hardness)
- Lock Washers: Feature radial convex outer surface and bevel tooth inner surface for 100% locking
Applications
| Industry | Use Case |
| Automotive | High-strength applications in engines and heavy-duty components |
| Mechanical | Connecting mechanical parts, circuit boards, transmissions |
| Energy | Power generation equipment and transmission line connections |
| Construction | Building structures, shipbuilding, petrochemical equipment |
Material Specifications
| Material | Properties |
| Aluminum | Excellent thermal/electrical conductivity, soft nature requires careful processing |
