3/8 - 5/16"-18 Shoulder Bolts - 304 Stainless Steel

3/8"-18 Stainless Steel Shoulder Bolts

Shoulder Diameter - Thread Size: 3/8" - 5/16-18

3/8" Shoulder bolts are stainless steel machine screws with a shoulder between the thread of the screw and the head of the part.

  • Non-threaded shoulder extends out of the surface of the application site
  • Allowing the bolts to act as:
    • Dowels
    • Shafts for moving parts
    • Axles
    • Guides for sliding pieces of an assembly
  • 304 Stainless steel is corrosion and rust resistant
  • Ideal for long lasting fresh water environments

Shoulder screws in this selection feature a Socket Drive and a Knurled Head, allowing for installation with a Hex or Allen bit or your fingers.

Sizes Listed As:
