The button is a type of fastener that joins two pieces of fabric together by sliding through a hole in the material. A button can be made from a variety of materials, including plastics and metals. Buttons are often used in clothing and fashion to add a decorative element and functionality. They may also be found in bags and other containers, or serve as an ornamental element on a piece of furniture or other object. They can also be used to make a piece of art or studio craft, and are sometimes even found in archaeological sites.

There are many different types of screw head, including wood screws, Phillips heads and Torx heads. The type of head that you choose depends on the materials you are working with and the size of the threaded end. The type of head that you choose will also influence the torque specifications of the screw. The head of a screw is the part that you use to hold the screw in place, so it is important to know which head will work best for your application.

One of the most common types of screw head is a socket button cap screw. These fasteners have a low domed head and a smaller bearing surface, making them ideal for applications where a flush finish is required or there is limited space. They have a hexagonal socket in the head that accepts a drive tool, such as an Allen wrench, for installation and removal.

These types of fasteners are available in a wide range of sizes and finishes, and can be used to secure almost any type of material. They are especially useful when a tight fit is necessary, such as in the case of a machine assembly or a die casting. Button head socket cap screws are also suitable for applications where the clamping material is too thin to countersink the screw.

Button head bolts have a unique shape that provides greater strength and torque resistance than other types of bolts or screws. This makes them an excellent choice for heavy-duty tasks, such as securing large machinery or working with thick materials like steel alloys. They are also often used in automotive repairs and maintenance, furniture assembly and other light industrial projects that require durable, aesthetically pleasing hardware solutions.

Metric and ISO 7380 Button Socket Cap Screws have a larger diameter face that distributes force more evenly than other types of screw heads. This allows them to achieve higher torque specifications than other screw head styles, without sacrificing their sleek appearance. In addition, the threaded end of these bolts can be recessed into a socket to prevent accidental disconnection. Metric and ISO 7380 Button Socket Head Cap Screws can be fastened and removed using a standard Allen wrench, or a hex key.
