Boxer 5/8" x 3" Square Trailer Pins (6-Pack) - Nickel-Plated Heavy‑Duty Locking Hitch Pins

Built from high-strength steel and finished with a corrosion-resistant nickel plating, these 3" x 5/8" pins deliver dependable retention for trailers, lawn tractors, farm implements, tents, and more. Sold in a convenient six-pack, they give you spare, replaceable pins for multiple rigs and spare usage without needing tools to install or remove. Boxer, a USA company founded in 1991, manufactures these pins to meet the routine demands of towing, hauling, and outdoor work where a secure, low-maintenance connector matters.

How do these pins hold a trailer or coupler securely?

Each pin inserts through aligned holes in the hitch or coupler and uses a locking mechanism or strong tension to resist unwanted movement. The square head and snug shaft diameter minimize rotational play, while the nickel plating helps the pin slide smoothly into place even after repeated use.

• 5/8" diameter fits common hitch and clevis hole sizes.
• 3" shaft length accommodates many coupler thicknesses and brackets.
• Square head prevents spinning and improves grip during installation.
• Firm retention reduces rattling and accidental disengagement.

Will these pins resist rust and outdoor wear?

The pins are nickel-plated to form a protective barrier against oxidation and surface corrosion, which extends service life in outdoor environments. While plating significantly improves durability, regular inspection and occasional cleaning will keep the pins operating at peak performance.

• Nickel finish lowers corrosion risk from moisture and road salt.
• High-strength steel core provides structural wear resistance.
• Smooth surface sheds dirt and eases insertion and removal.
• Suitable for seasonal storage and repeated outdoor use with basic maintenance.

How easy are these pins to install and remove during daily use?

Designed for quick, tool-free operation, each pin slides through mounting holes and locks into place with hand pressure or a simple clip depending on your hitch setup. That fast action makes hitching and unhitching quicker when moving trailers, mounting lawn equipment, or switching implements in the field.

• Tool-free insertion and extraction for faster hookup times.
• Square head offers secure finger or wrench leverage when needed.
• Pack of six ensures spare pins are available when swapping equipment.
• Compatible with common clevis pins, couplers, and shaft locking setups.
