Nuts, Bolts & Security Hardware

The right fasteners are the difference between a sign that stays put and one that ends up on the ground. Sign Kings offers a comprehensive selection of Nuts and Bolts specifically engineered for the signage industry. This collection features heavy-duty galvanized steel hex bolts and carriage bolts that resist rust and corrosion in the harshest outdoor environments. For high-traffic or high-risk areas, we specialize in vandal-resistant and tamper-proof hardware, including one-way bolts and breakaway nuts that prevent unauthorized removal. Don’t forget the details—our UV-resistant nylon washers are essential for protecting the face of your aluminum signs from "bolt-head circular scratching" and ensuring a professional finish every time.
