Titan part 0293489 is a hex nylon-insert locknut used to secure threaded fasteners on compatible Helix FR and Helix VR sprayers. When original nuts become lost, damaged, or stripped, they can compromise the secure assembly of critical components. This locknut restores proper fastening and ensures components remain securely attached during operation.
Hex Nylon-Insert Locknut for Helix FR and VR Sprayers
The Titan part 0293489 Hex Nylon-Insert Locknut is a precision fastener designed for use in Helix FR and Helix VR sprayers. This locknut features a nylon insert that provides vibration-resistant locking action, ensuring that bolted connections remain secure during sprayer operation. The hex shape allows for easy installation and removal with standard wrenches.
Using incorrect or damaged nuts can lead to loose components, vibration issues, or assembly failures. Replacing with the proper OEM nylon-insert locknut ensures secure fastening, proper clamp load, and maintains the structural integrity of the sprayer assembly even under high-vibration conditions.
Fastener Insight: The nylon insert in these locknuts deforms as the nut is tightened, creating friction against the bolt threads that resists loosening from vibration. This makes them ideal for sprayer applications where constant vibration is present.

Frequently Asked Questions
A nylon-insert locknut is a specialized fastener with a nylon ring embedded in the top of the nut. As the nut is threaded onto a bolt, the bolt passes through the nylon insert, which deforms and creates friction against the threads. This friction resists loosening from vibration, making these nuts ideal for applications like sprayers where constant vibration occurs. The nylon insert also helps seal the threads against moisture and contaminants.
Signs that your locknut needs replacement include: stripped or damaged threads, visible wear or deterioration of the nylon insert (the insert should be intact and provide resistance when threading), the nut spinning freely on the bolt without the typical locking resistance, corrosion that weakens the nut, or the nut missing entirely. If the nylon insert no longer provides friction, the nut has lost its locking capability and should be replaced.
Nylon-insert locknuts are generally considered single-use fasteners. The nylon insert deforms permanently during initial installation, and its locking effectiveness is significantly reduced after removal. For critical applications, replacement with a new nut is recommended to ensure proper vibration resistance. While they may appear reusable, the reduced locking capability can lead to loosening under vibration. The 0293489 locknut is inexpensive insurance against potential assembly failure.
Yes, the 0293489 locknut is designed to fit both Helix FR and Helix VR models. These sprayer series share common fastener specifications for the applications where this locknut is used. Always verify compatibility with your specific model and the bolt size you are matching.
