The Titan 590-506 Flat Washer is an OEM flat washer used in bolted joints across a wide range of Titan sprayers and stripers. It distributes the clamping load of a screw or bolt over a larger surface area, preventing embedment into soft materials and reducing the risk of loosening from vibration.
Over time, washers can become crushed, deformed, corroded, or lost during maintenance. Using a missing or damaged washer can lead to reduced clamp load, loosening of fasteners, and eventual component misalignment or failure. Replacing with genuine Titan 590-506 ensures proper load distribution, correct stack height, and reliable joint integrity.
| Load distribution | Spreads clamping force over wider area |
|---|---|
| Surface protection | Prevents damage to mounting surface |
| Spacing | Maintains correct component positioning |
| Deformation / crushing | Washer no longer flat |
|---|---|
| Corrosion | Rust or chemical attack weakens the washer |
| Missing washer | Lost during previous service |
| Thinning / wear | Reduced thickness from fretting or abrasion |

When replacing a flat washer, consider inspecting or replacing these associated components.
Inspect the fastener threads for damage or corrosion; replace if necessary.
If the application uses a split lock washer, replace it when replacing the flat washer.
Check the nut for stripped threads; replace if the nut does not thread smoothly.
