Nuts are threaded fasteners with internal threads designed to mate with bolts or screws to secure mechanical components. As critical elements in assembly systems, nuts provide removable joints that maintain structural integrity under various operational conditions. Their importance spans across industries requiring precision engineering, vibration resistance, and load-bearing capabilities.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Hex Nuts | Standard six-sided design with coarse/fine threads, economical and versatile | General machinery assembly |
| Lock Nuts | Integrated anti-loosening features (nylon insert, distorted thread) | Automotive powertrain systems |
| Flange Nuts | Integrated washer face reduces surface pressure | Sheet metal applications |
| Weld Nuts | Projection weld design for permanent metal joining | Steel structure fabrication |
| Cap Nuts | Protective enclosure for threaded ends | Exterior architectural components |
Typical nut configurations feature a prismatic or cylindrical body with chamfered corners. Key structural elements include:
| Parameter | Importance |
|---|---|
| Tensile Strength (800-1200 MPa) | Determines load capacity in clamping applications |
| Hardness (HRC 20-39) | Affects wear resistance and torque performance |
| Thread Class (6H, 4H) | Defines fit precision with mating bolts |
| Vibration Resistance | Critical for dynamic load applications |
| Corrosion Resistance | Measured via salt spray testing ( 72h) |
