Scraper Blade Bolts. Ground Engagement Bolts. Cutting Blade Bolts. No matter what you call them, Plow Bolts are the workhorse of the fastener industry used to bolt a leading blade edge to a plow board on heavy equipment like bulldozers, snow plows, road-grading equipment, and agricultural plows. Earnest carries a full line of Plow Bolts from Grade 5 and 8 up to our E9 170m high-strength Dome Head Scraper Bolts — all engineered to withstand the rigors of the most extreme conditions.

#3 Flat Head Plow Bolt – Grade 5

  • Used with smaller equipment – mini-excavators and skid-steer loaders
  • Provides a flush mount and zero clearance
  • Diameter sizes range from 3/8 to 7/16
  • Meets ANSI B18.9 specifications
  • #3 Dome Head Scraper Bolt – Grade 8

  • 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
  • Smaller transition angle on the corners of the square provides for a greater resistance against spinning in the hole during installation
  • Head design will fit in all applications designed for Caterpillar 1 1/4”
  • Available diameter 5/8” to 1 3/8
  • Based on ANSI B18.9 specifications
  • #3 Dome Head Scraper Bolt – Grade E9 170M

  • Grade E9 bolts are manufactured to a higher hardness and greater strength than Grade 8 for more demanding applications
  • Tensile strength of 170,000 psi minimum exceeds Grade 8 strength levels
  • Higher hardness and strength, along with special domed head design, provides added wear resistance
  • Rockwell hardness of Rc 37/42
  • Sizes are 1 1/4” and 1 3/8”
  • Size 1 1/4” is offered in a raised shoulder
  • Earnest offers a raised shoulder scraper bolt in the 1 1/4” size
  • Based on ANSI B19.9 specifications
  • #3 Oversized Head Plow Bolt – Grade 5

  • Popularly used for snow-plow blades
  • Threaded to the head to fit a variety of grip ranges
  • Oversized head provides versatility in using a blade manufactured to accept a larger head to a smaller diameter mounting device
  • The larger head diameter provides a greater wear area for increased life
  • The 3/8” size has the head dimensions of the corresponding 7/16” size, and the 7/16” size has the head of the 1/2” size plow bolt
  • Meets ANSI B18.9 specifications
