Socket Set Screws are generally used to secure an object within or against another object. Set screws are often headless, meaning that the screw is fully threaded and has no head projecting past the major diameter of the screw thread. Also included in Hillman assortment #4652 / label #369.

  • FOR MECHANICAL APPLICATIONS: Ideal for use in confined areas where the head needs to be flush or below the surface
  • HEX SOCKET DRIVE: Prevents slippage during installation
  • CORROSION-RESISTANT FINISH: Heat-treated zinc combines lasting durability with strong corrosion protection
  • PRE-DRILLING RECOMMENDED: For installation, drill a hole in the material that matches the diameter of the bolt
  • Socket head set screw is for mechanical applications
  • Head treated for toughness and durability
  • Socket drive prevents slippage during installation
