Nylon Insert Lock Nuts are hex nuts with a nylon band to help lock the fastener in place to prevent unwanted movement.

Nylon Lock Nuts in this selection are made from lightweight and durable aluminum. Aluminum Lock Nuts are corrosion resistant, lightweight, and non magnetic. As a metal, aluminum is valued for its high strength-to-weight ratio making it a common fastener material in the automotive, aerospace, and general machinery industries.

Important: We recommend not mixing metals; aluminum fasteners should be used with aluminum fasteners. For more information, please read our article on the subject HERE.
