(10 pcs) 1-1/4"-7 X 4", Plow Bolts, Dome Head, 3 Head, Full Thread, Grade 9 Steel, Plain

1-1/4"-7 X 4", Plow Bolts, Dome Head, #3 Head, Full Thread, Grade 9 Steel, Plain#3 Dome Head Plow Bolts are specially designed to provide added ease of assembly and greater resistance to failure in service as compared to a standard flat head design. 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. Two strength levels are available (depending on size and availability): Grade 5 (per SAE J429) - 120,000 psi minimum Tensile Strength Standard Duty, Good Strength to Toughness Ratio Grade 8 (per SAE J429) - 150,000 psi minimum Tensile Strength Heavy Duty, Best Strength to Toughness Ratio
