Class 10.9 M16 black finish high tensile plow bolt and nut
Plow bolts date back to about 1850 and are used to attach the plow share (blade) to the frog (frame) and allow earth to pass over their heads without obstruction to the moldboard. They are also used to fasten the blade to bulldozers and motor graders. Plow bolts have a small round countersunk head and a square neck—the width of the square (measured across the flats) is the same size as the nominal diameter of the bolt. The top of the head can be flat (for plows) or dome (convex) shaped (for dozers/graders); the conical (tapered) bearing surface of a plow bolt is 80°.
