1/4-28 Fine Thread 18-8 / 304 Stainless Steel Flat Head Socket Cap Screws.

  • 1/4"-28 Fine Thread Flat Head Socket Screws are Sometimes Called Flat Socket Head Cap Screw, Socket Screws, Allen Flat Socket Bolts or Flat Socket Machine Screw.
  • A Fine Threaded Flat Socket Head Cap Screw is a Fastener Driven by a Socket Hex Allen Wrench.
  • The Hexagonal Drive or Hex Key L Wrench Allows For Stronger Tightening Compared to Screws that use a Phillips or Flat Head Screw Driver That Sometimes Tend To Strip The Head Of The Screw.
  • Flat Head Cap Screws are Made to Fit Flush When Installed.
  • We Carry Flat Socket Screw Bolts in 18-8 / 304 Stainless Steel Which Is More Corrosion Resistant.
  • These are the Most Popular Flat Head Socket Cap Allen Wrench Screws for Many Production Applications.
  • Right Hand Thread, Fine Pitch, UNF
