Cap Nuts / Acorn Nuts

Add a finished, refined look to your hardware with our cap nuts and acorn nuts, designed to conceal exposed threads while enhancing your project's overall design. These decorative fasteners are ideal for visible installations—like iron straps, furniture, railings, and gates—where detail matters as much as function.

Crafted from solid iron or steel and available in a range of styles from rounded acorn caps to square and domed cap nuts, each piece is made to complement our bolts, washers, and brackets. Choose from hand-applied finishes such as blackened iron, oil-rubbed bronze, sealed rust, or natural steel to match your hardware and design aesthetic.

More than just a cover, these nuts serve to protect threads, prevent snags, and provide a clean, traditional appearance rooted in historical craftsmanship. Proudly made in the USA and finished to order, our cap nuts and acorn nuts are a small detail that make a lasting impression.
