5/16 - 1/4"-20 Shoulder Bolts - 304 Stainless Steel"

5/16" Stainless Steel Shoulder Bolts

Shoulder Diameter - Thread Size: 5/16" - 1/4-20

  • 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 freshwater environments

5/16" Shoulder bolts are stainless steel machine screws with a shoulder between the thread of the screw and the head of the part. 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.

A Shoulder Bolt is measured as Shoulder Diameter - Thread Size x Length of Shoulder
