Hex domed cap nut with a closed end. The domed profile fully encloses the protruding bolt thread, reducing the chance of scratches or accidental contact with the thread end. Where material and finish are appropriate, the closed end also helps limit exposure of the thread to moisture.

Available in carbon steel and stainless steel and offered with various surface finishes. Common applications include machinery, vehicles, railings and furniture. Please confirm thread size, pitch, length and finish when specifying to ensure the cap nut suits the intended bolt and environment. Specify any required material grade or corrosion-resistance needs when ordering.
