5/16"-18 Stainless steel knurled head socket cap screws are driven by an allen or hex wrench.

  • externally grooved cap head
  • can be driven by hand
  • cylindrical head
  • head diameter is nominally 1.5 times or more that of the screw shank (major) diameter
  • 316 Stainless steel offers superior corrosion and rust resistance
  • Ideal for marine and salt water environments
5/16"-18 Stainless steel (grade 316) knurled head socket cap screws corrosion resistance is greater than 18-8 stainless, which is why we recommend using 316 stainless steel fasteners for salt water application.
