Technical Ground Tillage Hardware and Fasteners

Subcategory dedicated to high-tensile fasteners and hardware (grade 8.8, 10.9, and 12.9) for ground-engaging agricultural tools. Inside you will find countersunk square-neck bolts (DIN 608 / UNI 6104), oval-head plow bolts, self-locking or flange nuts, and heavy-duty washers for plows, cultivators, harrows, and subsoilers. Engineered with precision threads and protective zinc or black-oxide coatings, these fasteners withstand intense mechanical shock, severe vibration, and shear forces, ensuring ultra-secure attachment of shares, points, and chisels to the implement frame.

Subcategories

  • Nibbed Plow Bolts

    Subcategory dedicated to specialized plow bolts with anti-rotation nibs for securing plowshares, points, shin pieces, and moldboards to the plow body. Featuring one or two nibs beneath the head that fit snugly into matching keyways on wear parts, these bolts prevent the shank from spinning during tightening or removal, making maintenance fast and straightforward. Manufactured from high-tensile steel (grades 8.8 and 10.9) with countersunk flat or domed heads, they sit flush with the working surface to minimize soil drag and protect the bolt head from premature abrasive wear.

  • 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.

  • Countersunk Conical Head Plow Bolts

    Subcategory dedicated to countersunk conical head plow bolts engineered for precision flush-mounting on shares, points, shin pieces, and moldboards. Designed with a calibrated conical taper, these bolts seat seamlessly inside matching countersunk holes on wear parts, creating an entirely smooth and uniform surface. This design eliminates any head protrusion that could cause unnecessary soil drag or debris snagging. Manufactured from high-toughness alloy steel in resistance grades 10.9 and 12.9, they deliver a tight, secure fit capable of withstanding heavy shear stress and severe impacts from rocks.

  • Shear Bolts and Breakaway Bolts

    Subcategory dedicated to shear bolts, breakaway bolts, and safety pins for plows, subsoilers, cultivators, and heavy tillage machinery. Engineered with calibrated shear points or precise tensile grades (such as grade 8.8), these sacrificial fasteners act as mechanical safety devices: when encountering buried rocks or immovable underground obstacles, the bolt shears cleanly. This immediate release allows the leg or working body to swing back safely, preventing costly structural damage or bending of the implement frame and reducing maintenance downtime in the field.
