Cap Nuts are fastening components featuring a domed or closed end, designed to protect exposed bolt threads while providing a finished appearance. Made from high-strength steel, stainless steel, or corrosion-resistant materials, they offer durability and reliable performance in various applications.
The closed-end design prevents dirt, moisture, and debris from entering the threads, reducing corrosion and wear. Cap Nuts are widely used in automotive, machinery, furniture, construction, and industrial applications where both protection and aesthetics are required.
