Socket Set Screw (12 Products)

Socket set screws, commonly known as grub screws, are headless threaded fasteners used by mechanics and manufacturers to secure rotating parts like pulleys, gears, and collars onto shafts. These fasteners rely on internal friction rather than a protruding head to hold components firmly in place within tight mechanical spaces.

Available Sizes and Types

  • Stainless steel socket set screws in M3, M4, and M6 dimensions
  • Fully threaded S.S 304 and imperial size grub screws
  • Large pack quantities ranging from 50 to over 40,000 pieces

How to Choose the Right Screw

When selecting a socket set screw, verify the shaft diameter and thread pitch required to match your application housing. Decide between metric and imperial dimensions based on your equipment specifications, and choose stainless steel material when corrosion protection is necessary for long-term reliability.
