SHENLIU Square Trailer Hitch Pins 1/4" 40-Pack — Zinc-Plated Carbon Steel with Wire Retainer for Wagons & Trailers

SHENLIU 40 PCS Square Trailer Hitch Pin set is a bulk pack of 1/4" carbon-steel square shaft locking pins with zinc coating designed to secure couplers, wagons, and light towing connections.

This set provides a high-volume, economical solution for hardware needs on farms, gardens, small trailers, and utility wagons. Each pin is formed from carbon steel and finished with a zinc plating to resist rust and extend service life. The square-shaft design coupled with a 360° rotating spring or wire retainer offers a reliable physical stop for common hitch and coupler applications, making these pins a practical choice for maintenance crews, hobbyists, and fleet operators who prefer to keep spare hardware on hand.

How do these pins secure a trailer or wagon coupling?

These square hitch pins slide through aligned holes in couplers and receiver tongues to physically lock two components together. The integrated wire or spring-retainer rotates or snaps to hold the pin in place and prevent accidental withdrawal under normal use.

• 1/4" square shaft fits many light-duty hitch and coupler holes.
• Zinc coating resists surface rust for outdoor use.
• Wire/spring retainer secures the pin without extra tools.
• Bulk quantity reduces downtime by keeping replacements available.

Will these pins withstand outdoor and farm conditions?

Constructed from carbon steel with a protective zinc finish, the pins are intended to handle typical outdoor exposures such as moisture and dirt. While they are rust-resistant, regular inspection and cleaning are recommended in harsh, corrosive, or saltwater environments to prolong performance.

• Carbon steel core provides strength for light- to medium-duty loads.
• Zinc plating offers corrosion resistance for garden and farm use.
• Recommended to keep spares and check wear on moving parts.

How easy is installation and removal during regular use?

The pins are designed for quick, tool-free insertion and removal: align the hitch holes, push the square pin through, and engage the rotating wire retainer. This user-friendly process saves time when hooking up implements, trailers, or transport wagons.

• 360° rotating retainer snaps into place to lock the pin.
• Compact design fits tight spaces on couplers and tongues.
• Lightweight pins are easy to carry with spare sets for quick swaps.

What applications and quantities are included in this pack?

This package includes forty identical 1/4" square trailer hitch pins, suitable for a wide range of light-vehicle and equipment connections. The bulk set supports fleet management, workshop inventory, or seasonal projects where multiple fasteners are needed at once.

• 40 pins per pack—ideal for bulk replacement and inventory.
• Compatible with small trailers, garden wagons, utility carts, and light machinery.
• Cost-effective choice for maintenance teams and renters.
