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)
- Large washers (Class A, C)
- Small washers (Class A)
- High strength washers for steel structures
- Spherical, conical, and square inclined washers
- Standard, light, and heavy spring washers
- Internal/external tooth/serrated lock washers
- Single/double ear stop washers
- Round nut stop washers
Metal Washers: Made from steel, copper, or aluminum with high strength and corrosion resistance. Ideal for high temperature, high pressure, and heavy load applications in machinery, automotive, and marine industries.
Non-metal Washers: Made from rubber or plastic with excellent sealing and shock absorption properties. Used in pipeline systems, electronics, and furniture.
Composite Washers: Combine metal and non-metal materials for superior strength, corrosion resistance, and sealing performance. Common in chemical and food processing equipment.
| Material | Properties |
|---|---|
| Aluminum | Excellent thermal/electrical conductivity, lightweight, corrosion resistant, soft and ductile |
| Titanium | High strength, requires special machining techniques like EDM with deionized water |
| Steel | Very strong, generates heat during machining, often processed with wire cutting |
| Brass | High tensile strength, easy to machine but requires slow cutting speeds |
| Industry | Use Case |
|---|---|
| Automotive | Engine components, high-strength connections |
| Mechanical | Equipment connections, transmissions, structural components |
| Energy | Power generation equipment, transmission line fixtures |
| Construction | Building structures, petrochemical equipment, shipbuilding |
