A pile of screws refers to a collection of screws, typically in bulk, stacked or grouped together. Screws are fasteners with a helical thread, used to join materials by turning them into place. A pile of screws may consist of various sizes and types, such as wood screws, machine screws, or self-tapping screws, depending on the intended use. These screws are commonly used in construction, carpentry, machinery, and DIY projects to secure components together.
