    The most tamper-resistant nuts we offer, these have a hex head that breaks away upon tightening, leaving a non-removable cone. They can be installed using a standard wrench. Use them to reduce the risk of unwanted removal for objects in public spaces such as signs, lighting fixtures, and displays.
    Zinc—Zinc and zinc-plated alloy steel nuts are corrosion resistant in wet environments.
