Size 2 of nails, commonly referred to as 2-penny or 2d nails, are 1 inch in length.
The "penny" (d) designation, stemming from historical English pricing where "2d" meant two pence per 120 nails, directly indicates the length of the nail. As explained by SENCO, "That's how 2-penny or 2d came to describe nails that are 1 inch in length." This system scales, with larger "penny" sizes corresponding to longer nails; for example, "60-penny or 60d nails refer to 6-inch nails today."
Understanding the Nail Sizing System (Penny Sizes)
The "penny" system, denoted by the suffix 'd', is an old but still widely used method for specifying nail lengths. While it originally referred to the cost of 100 nails, it now serves as a direct indicator of length.
Here's a brief overview of how the penny system relates to nail length, with a focus on smaller sizes for context:
| Penny Size (d) | Approximate Length (Inches) | Typical Uses |
|---|---|---|
| 2d | 1 inch | Light trim, small crafts, securing thin materials |
| 3d | 1.25 inches | Small moldings, picture frames |
| 4d | 1.5 inches | Light framing, shingle siding |
| 6d | 2 inches | Fencing, general construction |
| ... | ... | ... |
| 60d | 6 inches | Heavy timber framing, specialized construction |
This table illustrates the relationship between penny size and length, using information consistent with the provided reference.
Practical Applications for 2d Nails
Given their short length, 2d nails are best suited for tasks requiring minimal penetration or for securing very thin materials where a longer nail might split the wood or protrude unnecessarily.
Common uses include:
- Crafts and Hobby Projects: Ideal for delicate woodworking, model building, or assembling small decorative items.
- Light Trim and Molding: Securing very thin trim pieces or small decorative moldings where a hidden fastener is desired and holding power requirements are low.
- Picture Frame Assembly: Joining narrow frame components without splitting the wood.
- Temporary Fastening: Holding small components in place while adhesive dries or prior to final assembly with stronger fasteners.
In conclusion, when you encounter "size 2 of nails" or "2d nails," you are referring to a nail that measures precisely 1 inch in length, making it suitable for a variety of light-duty and precision fastening applications.
