Iron Nails
Iron Nails hold together a long list of mid-game buildings. At the Iron Anvil one Iron Ingot makes 12 (16 with the Blacksmith perk), with the Iron Smithing technology (50 red) and Smithing mastery 6.
The Circular Saw takes 10, the Porter Stations and second-tier barricades and archer towers 8, the Fermentation and Wine Barrels 8 each, and the second Supply Pallet 12. Among recipes, only the second wooden gravestone and fence use them (2 each).

Notes
- The Circular Saw waits on them. It needs 10 Iron Nails, so the Wooden beams and everything after them come only once you forge iron.
- Three town shops sell them from tier II: the Furniture Maker (50, then 100), the Smithy (30, then 50) and the Builder (25, then 50).
- Studying them costs 3 Science and gives 20 red and 20 blue.
