#4-40 Socket Head Screws 316 Stainless Steel

#4-40 | 316 Stainless Steel Socket Cap Screws

Screw Diameter - Thread Pitch: #4-40


#4-40 Stainless steel knurled head socket cap screws are driven by an allen or hex wrench.

  • Commonly referred to as allen bolts, socket head cap screws, or socket head screws
  • 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
#4-40 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.
