316 Stainless Steel Socket Set Screws

316 Stainless Steel Internal Hex Drive Grub Screws

A Stainless Steel Set Screw is a type of screw generally used to secure an object within or against another object. The most common examples are securing a pulley or gear to a shaft. Set screws are most often headless (also called blind), meaning that the screw is fully threaded and has no head projecting past the major diameter of the screw thread. A blind set screw (known in the UK as a grub screw, quite possibly from its figurative resemblance to a soil-dwelling grub) is almost always driven with an internal-wrenching drive, such as a hex socket (Allen) socket The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object. It exerts compressional or clamping force through the bottom tip that projects through the hole.

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.

316 Stainless Steel is the finish of choice for superior corrosion resistance. 316 Stainless Steel fasteners have a higher corrosion tolerance than standard 18-8 / 304 Grade Stainless Steel, and are recommended for use in marine or salt water applications. 316 Stainless steel is used for fasteners that will be exposed to harsh environments

Socket Set Screws are driven with Hex Allen Keys.
