Countersunk Square Neck Plow Bolts

Subcategory dedicated to countersunk square neck plow bolts (DIN 608 / UNI 6104) for the precision mounting of plowshares, points, chisels, and moldboards. The square section beneath the flat countersunk head locks securely into matching square holes, preventing the bolt from turning during nut tightening and ensuring a rigid assembly under heavy mechanical strain. Manufactured from high-tensile heat-treated steel (grades 8.8 and 10.9), these bolts provide exceptional shear strength and impact resistance, with a flush-fit head profile that minimizes soil friction.
