Square Nuts Hot Dip Galvanized Grade 2

Hot Dip Galvanized Square Nuts

Four-Sided Square Nuts in Hot Dip Galvanized Steel


  • Four sided square nut
  • Greater resistance to loosening
  • More contact with surface of fastener
  • Less likely to lose their shape from constant loosening/tightening
  • Use with a flat washer to avoid damage from sharp edges
  • Square Nuts up to #10 are flat on both sides
  • 1/4" and up are beveled on one side
  • Hot Dipped Galvanized products should only be used with fasteners of the same material
  • Sizes listed below as: Internal Diameter - Thread Pitch
  • Due to the finishing process for Hot Dip Galvanized fasteners, it is recommended to only use Hot Dip Galvanized fasteners with Hot Dip Galvanized fasteners and not mix metals. This can create threading and durability issues.
