Application
1.Excellent Vibration & Loosening Resistance
The integral flange design maximizes contact area and friction, effectively absorbing vibration and dynamic loads to prevent loosening and enhance safety.
2. Uniform Load Distribution
Disperses clamping force evenly to prevent pressure concentration, protecting mating surfaces—especially on soft or thin materials—from crushing or deformation.
3. Superior Surface Adaptability
Compensates for surface irregularities and maintains a secure fit even on inclined or non‑perpendicular surfaces for consistently reliable connections.
4. Quick & Easy Installation
One‑piece design eliminates separate washer handling. Allows one‑handed operation, significantly speeding up assembly and reducing labor effort.
5. Low Maintenance & Long‑Term Reliability
Professional galvanizing provides corrosion resistance, minimizing the need for periodic inspections and re‑tightening over extended service life.
