Steel Screws

Steel Screws are forged at the Steel Anvil: one Steel Ingot makes 8 (10 with the Blacksmith perk), with the Steel Smithing technology (120 red, 15 blue) and Smithing mastery 11.

They hold together the last tier of buildings: 12 for the Assembly bench III and the Smithy II, 8 for the Large Chest, the Lathe and Sewing machine extensions and each third-tier barricade and archer tower. In town the Smithy and the Furniture Maker each need 12 for tier III.
