Featuring a socket drive, cup-point geometry, and a durable zinc finish, these screws deliver reliable holding power in compact spaces.

  • Material: Alloy steel for strength and wear resistance
  • Finish: Zinc-coated for corrosion resistance
  • Point: Cup point provides positive contact and minimizes marring
  • Drive: Socket (internal hex) drive for easy, low-profile tightening
  • Size: 4-40 thread, 5/16 inch long
  • Applicable use: Ideal for securing components where vibration resistance and precise positioning are required

Tips for best results: use the correct hex driver size to avoid stripping, ensure threads are clean and lubricated as needed, and verify the application’s load and vibration conditions to select the appropriate screw length.
