BOLT MC Hardware Fuji-Lock Hex Nut

The BOLT MC Hardware Fuji-Lock Hex Nut is a metric locking nut (also called a Fuji-style lock nut or hex locknut) for motorcycle and powersports applications where fasteners must stay tight. It is made for critical hardware that can't be allowed to back out under vibration.

Key Features:

• Fuji-style locking design that helps the nut hold its position in high-vibration applications
• Made from zinc plated steel for corrosion resistance
• Standard hex profile that works with common wrenches and sockets
• Metric thread sizes that match factory-style motorcycle hardware
• Made by Bolt Motorcycle Hardware, a supplier focused on factory-style fasteners for motorcycles

Use these hex lock nuts to replace worn, damaged, or missing original hardware during repairs, rebuilds, and routine service. Choose the thread size and part number you need from the available options.
