The washer is a fastener used between the supporting surface of the bolt, screw or nut and the connected part, which can protect the surface of the connected part, prevent the fastener from loosening, and serve other special purposes.
- Flat washers - Class C, large washers (class A and C), small washers (class A)
- Spring washers - Standard, light, heavy, internal/external tooth lock washers
- Special washers - Spherical, conical, I-steel square inclined, channel steel square inclined
- Stop washers - Single ear, double ear, outer tongue, round nut
Flat washers increase contact area and disperse pressure to prevent soft materials from being crushed. Spring washers provide tension after tightening to increase friction between nut and bolt. Lock washers consist of two washers with bevel tooth surfaces that prevent loosening through relative dislocation when vibration occurs.
| Industry | Application |
|---|---|
| Automotive | High-strength applications like engines and heavy-duty machinery |
| Mechanical | Connecting mechanical parts, circuit boards, engines, transmissions |
| Energy | Power generation equipment and transmission line connections |
| Construction | Building structures, shipbuilding, petrochemical equipment |
| Material | Characteristics |
|---|---|
| Aluminum | Excellent thermal/electrical conductivity but soft, may produce buildup during processing |
| Titanium | Requires EDM machining with deionized water to control heat |
| Steel | Very strong, generates significant heat during processing |
| Brass | High tensile strength but requires slow cutting speed |
Made of 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.
Made of rubber or plastic with excellent sealing and shock absorption properties. Used in pipeline systems, electronic equipment, and furniture where sealing is critical.
Combine metal and non-metal materials for strength, corrosion resistance, and sealing. Common in chemical and food processing equipment.
