The Titan 856-002 Lock Washer is an OEM split‑ring spring washer used under screw or bolt heads to prevent loosening from vibration. It exerts a continuous spring force that maintains tension even when the fastener experiences shock or cyclic loading.
Over time, lock washers can lose their spring tension (take a permanent set), become corroded, or go missing during maintenance. A flattened or missing lock washer allows fasteners to back out, leading to loose components, misalignment, and potential equipment damage. Replacing with genuine Titan 856-002 restores vibration‑resistant clamping, ensures fastener retention, and reduces the need for frequent retightening.
| Vibration resistance | Maintains tension under machine operation |
|---|---|
| Fastener retention | Prevents screws from backing out |
| Clamp load maintenance | Compensates for minor settling |
| Flattened / loss of spring | Washer no longer has spring action |
|---|---|
| Corrosion | Rust or chemical attack |
| Missing washer | Lost during previous service |
| Reassembly after repair | Always install new lock washer |
