A Carriage Bolt Has A Square Shoulder Under A Rounded Head Which Resists Turning When The Nut Is Tightened Or Removed. They Are Good For Wood-To-Wood Connections When The Head May Not Be Accessible For Tightening. They May Be Used In The Construction Of Docks, Swing Sets And Decks As Well As Other Surfaces Where A Smooth Finish Is Needed.

  • Used whenever a smooth finish surface is needed so that nothing becomes snagged on the fastener.
  • Zinc plating, retards the corrosion rate in a normal atmosphere.
