| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan 5/16" split lock washer used to prevent fasteners from loosening due to vibration in compatible AirCoat, PowrCoat, and SprayTech systems. |
| Function | Installed under the head of a bolt or under a nut to provide spring tension that resists loosening caused by vibration, thermal cycling, or dynamic loads. The split action creates tension that resists rotation, maintaining clamping force on critical fasteners. |
| Replacement Indicators | Signs that replacement is needed include fasteners that frequently loosen, visible flattening of the washer (loss of spring gap), corrosion, cracks, or during routine disassembly of bolted joints. |
| Service Guidance | Lock washers can lose their spring tension after being compressed. Always install a new washer when servicing to ensure proper locking action. Inspect washers for signs of fatigue, cracking, or loss of spring tension. |
| Industrial Applications | Professional painting, fine finishing, and applications requiring reliable vibration-resistant fastening. |
| Compatible Models | AirCoat 423, AirCoat 620, PowrCoat 630, SprayTech EP2300/EP2300SE/EP2400/EP2510/EPX2305, Titan EPX2455/EPX2555. |
