Nails are a type of ammunition, usable only by the Nailgun. They are consumed when using the Nailgun as an offensive weapon (by left-clicking); upgrading/repairing a block (by right-clicking) will not consume any Nails.
Nails can be cast in a Forge, using a Nail Mold, and found in various locations (most commonly found in garageStorage). Nails can be scrapped or melted in a Forge to produce iron and have a maximum stack of 500.
