Replace your old washers with wedge-locking washers – and forget about bolt loosening once and for all.
Why Do Traditional Locking Methods Fail?
| Method | Limitations |
|---|---|
| Spring Washers | Prone to failure under high torque and high vibration conditions |
| Threadlocker Adhesives | Difficult to remove, not heat-resistant, unsuitable for repeated maintenance |
| Double Nuts | Require precise preload during installation, complicated and time-consuming |
How Do Wedge-Locking Washers Work?
The principle is simple yet highly effective:
- Two washers form a pair with wedge-shaped cams on the inner faces.
- When tightened, the cams interlock securely with each other.
- Under vibration, the two washers slide slightly relative to each other.
- The wedge effect automatically compensates for preload loss – the more vibration, the tighter they lock.
✅ No reliance on friction
✅ No adhesives required
✅ No impact on installation efficiencyPure mechanical self-locking – long-term protection against loosening.
How Do They Extend Maintenance Cycles?
- Outstanding performance under high-frequency vibration and dynamic loads
- One installation, long-term effectiveness – no frequent shutdowns for retightening
- Significantly reduces labor costs for maintenance
- No equipment modifications and no bolt replacements – simply replace your existing washers directly
Important Installation Tips
| Step | Instruction |
|---|---|
| ① | Always use as a pair – never use a single washer alone |
| ② | Wedge cams facing each other; flat serrated faces against the bolt head/nut |
| ③ | Ensure contact surfaces are clean and flat |
| ④ | Tighten to the specified torque – do not over-tighten |
| ⑤ | Select washers matching the bolt diameter |
