These Grade 8 plow bucket-tooth bolts have a locking key that holds the bolt as the nut is fastened. Used to secure heavy equipment parts these bolts have smooth angled heads to sit flush within their countersunk holes. The hole must first be countersunk with the chamfered edge in order to sit flush. These bolts come in a black oxide finish which is corrosion resistant in dry environments.

• 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
