  • Purpose: The primary function of a screw is to create a strong and secure joint between two or more components by exerting clamping force when tightened into a threaded hole or nut.
  • Design: Screws consist of three main parts: the head, the shank (or shaft), and the threads. The head is typically wider than the shank and may be slotted, Phillips, Allen, or Torx shaped to accommodate different types of screwdrivers or wrenches. The threads, located along the shank, provide the gripping action necessary for securing the screw in place.
  • Material Composition: Screws are made from various materials, including steel, stainless steel, brass, aluminum, and nylon. The material choice depends on factors such as the application, environmental conditions, and load requirements.
  • Types: There are many types of screws available, each designed for specific applications. Common types include wood screws, machine screws, self-tapping screws, sheet metal screws, and concrete screws. Each type has unique features such as thread type, head shape, and point design tailored to its intended use.
  • Installation: To install a screw, it is inserted into a pre-drilled hole or threaded nut and tightened using an appropriate screwdriver or wrench. The screw’s threads engage with the mating threads in the hole or nut, creating a secure joint.
  • Applications: Screws are used in countless applications across industries, including construction, manufacturing, automotive, electronics, and furniture assembly. They are essential for securing components, attaching parts, and providing structural support in various mechanical systems.
