1-8 x 3-1/2 Inch Coarse Plain Grade 8 Dome Head Plow Bolt

232.1.312

Though available year-round, there?s no better time to get new plow bolts than before the winter season is in full swing. Plow bolts have a countersunk head and square neck that prevent turning when a nut is tightened or removed. Traditional applications can be found in plows and various pieces of heavy equipment.
  • Thicker domed head provides greater wear resistance
  • Specialized head diameter provide for a tighter fit in countersunk holes
  • Head design will fit into all applications designed for # 3 Heads
  • 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
  • Tighter tolerance on the body diameter for sizes 5/8 and larger, minimizes the potential of the bolt moving in the hole, which can result in the assembly coming loose and causing rounding out of the installation holes
