About
- Penny size is bullshit. Penny size applied to different nail types means a different length!
- 1" is 2D [1]. Note that penny size came historically from cost of the nails in pennies. So the length is not proportial to D size. [2]. The only thing we know is that the larger the D number, the larger the nail.
- 10D is 3" long - [3]
- Joist hanger nails do not seem to have D size attached to them - this one is 1.5" [4]
- This 8D is 1.5" long [5]. Is that an error? Chart says 8D is 2.5".
- 3.5" common nail, galvanized. 16D [6]
