Grade 420 (Purple Liquid)

        
Small diameter fasteners, Low strength for easy adjustments
        or Disassembly.  Easy removal with simple hand tools.

        
Nuts N' Bolts 420 is engineered to eliminate vibrational loosening
        of set screws, cap screws, and machine screws while allowing
        for easy disassembly or adjustment.  It is recommended for fasteners
        with engagement L/D ratios of one or greater.  This grade replaces
        expensive mechanical locking devices.

        
The low strength characteristic of Nuts N' Bolts 420 allows
        easy adjustments of assembled parts with simple hand tools.
        It is non-migrating with predictable torque/tension and lubricity
        characteristics.
