Black Round Clavo Nail for Doors and Chests Ø 23mm

Black Round Clavo Nail for Doors and Chests

Rustic Decorative Nail with a Hammered Appearance

The low domed head has a subtly irregular face covered with small depressions resembling individual hammer marks. Its black finish emphasises the texture and creates a strong contrast against natural timber.

A straight pointed shank projects from the back of the head. A single large-head furniture nail can be used as an individual accent, while several pieces can form borders, regular rows or geometric arrangements.

The fitting is made from solid cast iron with a rustic black finish. It is a cast decorative component with a traditional blacksmith-made appearance rather than an individually hand-forged iron nail.

Suitable Applications

• Substantial timber doors, barn doors and garden gates.
• Chests, cupboards, cabinets, benches and furniture fronts.
• Wooden shutters, picture frames and mirror frames.
• Exposed beams, wall panelling and rustic timber structures.
• As a complement to black strap hinges, latches and door pulls.
• Film, theatre, cosplay and LARP props.

The nail is intended primarily for decoration. Do not rely upon it as the sole fastener for structural components, heavily loaded hinges or safety-critical joints.

Decorative Nails in Medieval and Early Modern Ironwork

Large-headed nails were used throughout the medieval and early modern periods. They connected timber components, secured strap hinges and held leather or metal coverings against doors, gates and chests. Their broad heads also helped prevent the shank from pulling through the attached material.

Visible nail heads soon became decorative features. They were arranged in rows, crosses and geometric patterns across church doors, castle gates and substantial domestic furniture. Round, faceted and rosette-shaped heads were particularly effective on Gothic and later Renaissance architectural ironwork.

The word clavo is Spanish for nail. In modern furniture and architectural hardware, it commonly describes decorative studs inspired by historical and Spanish colonial designs. This product follows that visual tradition but is not an exact reproduction of one particular archaeological find.

How to Install the Clavo Nail

• Mark the exact position before installation. Use a ruler, template or taut line when arranging several nails.
• In hard, dry or seasoned timber, drill a pilot hole approximately 0.10 inches or 2.5 mm in diameter.
• A slightly narrower hole may be suitable for softwood, although the nail should never require excessive hammering.
• Match the depth of the hole to the shank length of approximately 1 inch or 25.5 mm.
• Position the nail squarely and press it into the opening by hand as far as possible.
• Seat it carefully through a wooden block, thick leather or another soft protective pad.
• Do not strike the textured head directly with a steel hammer.
• For a purely decorative installation, a small amount of suitable timber-and-metal adhesive may provide additional retention.

Technical Specifications

All dimensions and weights are approximate. Owing to the manufacturing process, individual pieces may vary slightly in surface texture, edge shape, shade of black and minor casting marks.

Care and Safe Use

• Remove dust and ordinary dirt with a soft dry cloth.
• Dry the surface thoroughly after contact with water.
• For outdoor use, inspect the black coating periodically.
• Protect worn areas with metal wax or non-acidic conservation oil.
• Do not use wire wool, abrasive pads, acidic cleaners or aggressive rust removers.
• Do not drive the nail into stone, concrete, masonry or metal.
• Do not attempt to bend or straighten the cast-iron shank, as it may fracture.
• Wear safety glasses while drilling and installing the nail, and secure the workpiece firmly.
• Keep pointed nails out of the reach of children.
• Use rated screws, bolts or construction nails for load-bearing joints.
