This plow bolt secures the share or moldboard to the plow frame, using two integral lugs on the underside of the head to prevent rotation during operation. The bolt is installed from the wear side of the component, with the square or lugged shoulder engaging a matching recess in the part being fastened. A worn or loose plow bolt allows the share to shift, leading to uneven furrow depth and accelerated wear on the mounting holes. The manufacturer machines the head and lug geometry to match the original assembly's recess, ensuring the bolt seats fully and maintains clamp force under load. On reinstallation, clean the recess of debris and torque the nut to the specification for the assembly.
