Screws

A pointed metal fastener used in crafting to attach pieces of material together.

Notes

Screws are a pointed metal fastener, crafted from metal bars, that serves as a fundamental component in many advanced industrial machines and structures. They are used in recipes such as the Assembly Line, Blast Furnace, Boiler, and Composite Lumber workstations, making them a high-demand intermediate product for mid-to-late-game industry. Because screws appear in so many critical builds, maintaining a steady stockpile is wise to avoid production bottlenecks when expanding your factory.
