Hex screws are fasteners characterized by their hexagonal heads, which allow for easy tightening and loosening using a wrench or socket. They are commonly made from materials like steel or stainless steel, providing strength and durability for various applications. Hex screws are widely used in construction, automotive, and machinery assembly due to their reliable grip and resistance to stripping. These screws come in various sizes and lengths, making them versatile for different projects. They can be used with nuts for added security or in conjunction with washers to distribute load. Hex screws are essential components in many mechanical and structural applications.
