What is a Screw?

Screws are mechanical fastening components that are used to securely connect parts together by rotating them. Screws have a helical groove (thread) on a cylindrical shaft, which allows for the connection to be firmly held together. Depending on the material and application, screws come in various sizes, shapes, and thread types (e.g., metric or inch threads).

Types of Screws:
・Bolts: Often used in conjunction with external nuts for connections that need to withstand significant forces.
・Screws: Types of screws that are screwed directly into parts without the need for nuts, such as wood screws or machine screws.
・Cap Screws: Screws with a flat head, often tightened with tools to provide a strong and secure connection.
Features:
・Fastening Strength: Screws provide strong connections by applying a tightening force, minimizing gaps between components.
・Easy Removal: Screws can be easily removed and reused with the right tools.
・Variety: Screws come in various types, sizes, and materials (steel, stainless steel, plastic, etc.), allowing for specific use case selection.
