ND Patch Locking Patch technology provides a pre-applied, dry-to-touch locking solution engineered for reliable thread retention in demanding industrial applications. The resilient nylon patch is permanently fused to the fastener, delivering immediate locking performance without curing time or liquid adhesives. Designed to resist vibration loosening, ND Patch maintains fastener integrity while allowing repeated adjustment and reuse. It withstands extreme temperatures, oils, fuels, solvents, and harsh operating environments. Ideal for automated assembly systems, ND Patch eliminates the need for lock washers, cotter pins, and secondary locking components, improving assembly efficiency and reducing overall installation costs
