STEEL Not Plated
PLOW BOLTS are for use in a countersunk hole
so that the heads will fit flush with the surface.
The heads are so designed to prevent the bolts
from turning when the nut is applied.
No. 3 head is the most popular Plow Bolt. Its
square neck gives it a perfect fit on the face of
the plow share.
