Plow Bolt
Plow bolts have a flat or slightly domed countersunk head with a square section under the head that prevents rotation. They are used in earthmoving equipment — bulldozer cutting edges, grader blades, bucket lips — where the bolt head must sit flush with the wear surface.

Buyer Questions
Frequently asked questions
How does a plow bolt resist loosening from impact and vibration?
The square or fin section under the countersunk head bites into the wear plate, preventing rotation. Combined with a serrated-flange or all-metal locknut on the back side, this provides good resistance to the severe vibration of earthmoving service.
