Set Screws

Set Screws are headless fasteners designed to secure an object within or against another object, typically without protruding. At Skdin, we provide high-quality Set Screws in various point styles and materials for securing pulleys, gears, knobs, and other components to shafts. These headless screws apply compression force to prevent relative movement between components and are available with different drive types including hex socket, square, and slotted. Our set screws are manufactured to precise standards and are ideal for applications where a flush surface is required or space is limited. Explore our comprehensive selection of set screws to find the perfect solution for your shaft-securing applications.
