Plow Bolts, often called Scraper Blade Bolts or Cutting Edge Bolts, are used for bolting a leading blade edge to a plow board on heavy equipment like bulldozers, snow plows, road-grading equipment, and agricultural plows. They are available in a #3 Flat Head design in SAE J429 Gr.5 Material and in a #3 Dome Head design in SAE J429 Grade 8 Material for the heaviest duty applications.

  • Applications include mounting blades to plows for construction equipment and snow plows
  • Rounded head increases impact resistance and improves wear resistance
  • Deeper depth of square provides fuller engagement
  • Available diameter 5/8" to 1 1/4"
  • ANSI B18.9 specification
