Grade 5 plow bolts are used in medium-duty small or confined operational systems. They come in black oxide, which is corrosion resistant in dry environments, or zinc-plated finishes, which are corrosion resistant in wet environments.

Grade 5 dome-top plow bolts are used in medium-duty small or confined operational systems. They come in black oxide, which is corrosion resistant in dry environments, or zinc-plated finishes, which are corrosion resistant in wet environments.

Grade 8 dome top square neck plow bolts resist damage better than flat head bolts. They mount flush in tapered hole and fit into countersunk holes with chamfered edges. Their square-shaped neck prevents the bolt from turning while the nut is fastened. These bolts are used in small, heavy-duty, or confined operational systems. Black oxide bolts are corrosion-resistant in dry environments, while zinc-plated finishes have corrosion resistance for wet applications.

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.
