Plow Bolts | Grade 12.9 Plough Bolts for Reversible Plough

Overview

Plow bolts (also called plough bolts) are dedicated heavy-duty fasteners designed for agricultural tillage equipment, widely used to secure plow share, mouldboard, skimmer and other components on hydraulic reversible ploughs. Featuring a countersunk flush head and square neck, the bolt stays locked and will not rotate during tightening, avoiding protrusion that blocks soil flow while ploughing. We supply a full range of plow bolts together with matching nuts, for replacement and OEM service of reversible ploughs.
