Set Screws are also often used in applications where a flush installation and the look of the final assembly are important, such as furniture assembly. Socket Set Screws will run flush with the installation surface. They are often plugged after installation for a hidden fastener look. These qualities are what make set screws commonly used in applications where a flat surface is important, such as handles, grips, surfboard fins, and furniture or machine assembly. Because a flush surface is important on complex machines, Set Screws are also commonly used in gears, pulleys, and wheel in machines with moving parts.
