Copper Head Nail
A copper head nail is a type of nail distinguished by its enlarged, often cup-shaped, copper head. These nails are primarily used in roofing applications, specifically for securing asphalt or wooden shingles, slate, and other roofing materials.
Material:
The nail consists of a steel shank with a head made of copper or a copper alloy (typically brass). The shank provides the necessary strength for penetration, while the copper head offers corrosion resistance and a specific aesthetic.
Purpose:
- Roofing: The primary purpose is to securely fasten roofing materials to the roof deck.
- Corrosion Resistance: Copper is highly resistant to corrosion, preventing rust stains and deterioration of the roofing material, especially important with asphalt shingles.
- Aesthetic Appeal: The copper head provides a traditional, visually appealing finish, often desired in historic restorations or high-end roofing projects.
Function:
The enlarged head serves several functions:
- Increased Holding Power: The larger surface area of the head distributes the force of the impact, reducing the likelihood of splitting the wood or damaging the roofing material.
- Weather Sealing: The head, when properly driven, helps to seal the nail hole, preventing water ingress.
- Ease of Identification: The copper head makes the nails easily visible, aiding in inspection and maintenance.
Usage Scenarios:
- Asphalt Shingle Roofing: Commonly used for securing asphalt shingles, particularly in areas where a traditional look is desired.
- Wooden Shingle/Shake Roofing: Effective for fastening wooden shingles and shakes, providing a durable and aesthetically pleasing finish.
- Slate Roofing: Used in slate roofing applications, offering a secure and long-lasting fastening solution.
- Historic Restoration: Frequently employed in the restoration of older buildings where maintaining the original aesthetic is crucial.
Common Types:
- Round Head Copper Nails: Feature a rounded head, providing a classic look.
- Square Head Copper Nails: Have a square head, offering a more robust appearance.
- Cupped Head Copper Nails: The most common type, with a cupped head that provides increased holding power and weather sealing. Variations exist in the depth and diameter of the cup.
- Ring Shank Copper Nails: Incorporate rings along the shank for enhanced holding power, particularly useful in softer woods.
- Smooth Shank Copper Nails: Have a smooth shank, suitable for general roofing applications.
Installation:
Copper head nails are typically installed using a hammer. Proper driving technique is crucial to avoid bending the nail or damaging the roofing material. The nail should be driven straight and to the correct depth, ensuring the head is flush with the surface of the roofing material.
