TOP LINK PINS

Top Link Pin – Heavy-Duty Pin for Tractor 3-Point Linkage Systems

Top Link Pins are essential fastening components used to connect the top link of a tractor’s 3-point linkage system to agricultural implements and attachments. These pins ensure stable alignment, secure load transfer, and smooth implement movement during lifting and towing operations. Designed for high load-bearing capacity and vibration resistance, top link pins play a critical role in maintaining proper implement positioning and safe tractor operation.

Manufactured with precision machining and high-strength steel, top link pins deliver excellent durability, wear resistance, and long service life even under tough field and industrial conditions.

Material Grades & Surface Finishes

Our Top Link Pins are produced using premium materials for strength and corrosion resistance:

Material Grades:

• Carbon Steel (EN8 / C45) – High strength and wear resistance for general agricultural use

• Alloy Steel (EN19 / 42CrMo4) – Extra tensile strength for heavy-duty and shock-load applications

• Stainless Steel (AISI 304 / 316) – Corrosion-resistant for outdoor, wet, and marine environments

Surface Finishes Available:

• Zinc Plated (White / Yellow)

• Black Oxide

• Nickel / Chrome Plated

• Hardened & Ground Finish

• Passivated (for Stainless Steel)
