Set Screws are blind (headless) fasteners with an internal hex drive. It is this drive style that classifies Stainless Steel Screws in this selection as Socket Set Screws, which are driven by a hex bit or Allen wrench. Set Screws are used in a tapped hole, and tightened to hold an exterior object in place within or against another object, via friction between the point or end of the screw and the material that is being fastened.
Set Screws, also known as grub 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 are headless, which means that they will run flush with the installation surface. They are often plugged after installation for a hidden fastener look. These qualities are what make socket 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.
Stainless Steel Metric Socket Set Screws in A2 Stainless Steel offer the Fastener Industry standard for corrosion and rust resistance in Metric Fasteners, and are recommended for use in exterior applications, or those that are exposed to fresh water moisture.
