Cold forged bolts

Plow Bolts

Plow bolts are often used on road construction, agriculture, snowplow and other heavy equipment.  There are different styles of plow bolts each with a number identifying the style.  They are offered in different head types: flat, dome, contour, clipped and flat oversize are the most common.  # 3 Plow Bolts are the most popular.  They are available in Grade 5, Grade 8 or stronger materials.  The square neck or clipped head design holds the bolt in place, preventing the bolt from turning when tightening the nut during installation.
