PINAILER Square Trailer Pins 2-3/4" x 1/4" Pack of 20 — Zinc-Plated Carbon Steel, Clip-Lock

PINAILER pack of 20 square trailer pins are 2-3/4" long by 1/4" wide zinc-plated carbon steel hitch pins with a square shaft and retaining clip designed to hold coupler latches securely.

These trailer hitch pins offer a compact, straightforward fastener for securing coupler latches, accessories, and small agricultural or utility connections. Made from carbon steel with a protective zinc finish, the pins resist surface rust while the semi-flexible square shaft and clip provide repeated use without bending. Sold in a set of 20, they provide spares for multiple trailers, implements, or equipment projects.

How strong and durable are these PINAILER square trailer pins?

The pins are manufactured from carbon steel for strength and then zinc plated to help prevent corrosion from weather exposure. Their square profile reduces rotational slip when fitted into a square coupler or bracket, and the included clip locks the pin in place under vibration.

• Material: carbon steel core for tensile strength
• Finish: zinc plating for improved surface corrosion resistance
• Design: square shaft to minimize rotation in fittings
• Retention: included clip secures pin under movement

Will these pins fit my trailer or equipment?

Each pin measures 2-3/4 inches (length) by 1/4 inch (diameter), a common size for light trailers, utility carts, and many implement couplers. Confirm your coupler hole size and required working length to ensure compatibility before installation.

• Length: 2.75 inches overall for short-to-medium latch reach
• Width: 0.25-inch shaft diameter for standard 1/4-inch holes
• Fit check: matches many small trailer couplers and accessories
• Quantity: pack of 20 provides multiple spares or replacements

How easy are these pins to use during everyday hookup tasks?

The square shaft slides into typical coupler holes quickly and the clip snaps over the shaft to lock it. Because the pin and clip are simple, low-profile parts, they’re convenient to carry and swap when changing attachments or performing routine trailer hookups.

• Quick insertion: straight shaft for fast alignment
• Secure locking: clip holds pin from backing out
• Low maintenance: no complex mechanisms to clean or adjust
• Portable: light, easy to store in a glovebox or tool kit

What kinds of applications are these pins suitable for?

These pins are tailored for general-purpose attachment tasks where a 1/4" pin is appropriate. Use them on small trailers, lawn and garden equipment, carts, agricultural implements, and any simple coupler or bracket that accepts a square pin of this size.

• Trailer coupler latches on small utility trailers
• Accessory mounting and removable brackets
• Garden and lawn equipment quick-attach points
• Light farm implements and hobby machinery connections
