Hex socket screws, also known as Allen screws, are fasteners characterized by a hexagonal recess in their heads. This design allows for the use of a hex key or Allen wrench for tightening or loosening. They are commonly made from various materials, including steel and stainless steel, and are used in a wide range of applications due to their strength and reliability. These screws are often found in furniture assembly, machinery, and automotive components. Their design provides a clean appearance and minimizes the risk of stripping compared to traditional screw heads. Hex socket screws are available in various sizes and lengths to suit different needs.
