    Image of Product. Bottom orientation. Weld Nuts. Left-Hand-Thread Tube End Weld Nuts.
    These weld nuts prevent fasteners from backing out of assemblies that rotate counterclockwise. Their left-hand threads pair with left-hand screws and rods to stop the fastener from loosening as the assembly turns. Weld them to the end of a tube for a stronger connection than tapping the tube directly. Also known as tube adapters and weldable threaded tube ends.
