Features
- Secure Square and Arch-Loop Locking: Featuring a heavy-duty spring steel wire loop, these 1/4-inch diameter hitch pins snap firmly into place to prevent accidental decoupling. The square and arch-loop design provides extra clearance and stability compared to round pins, ensuring a secure hold on trailer couplers and PTO shafts even under high-vibration conditions.
- Corrosion-Resistant Zinc Plating: Each safety pin is forged from high-strength carbon steel and finished with a premium zinc coating. This provides a reliable barrier against rust and oxidation, making these pins ideal for long-term outdoor exposure on farm machinery, boat trailers, and garden tractors in all weather conditions.
- Universal Equipment Compatibility: With a usable length of 2-3/4 inches, these versatile shaft locking pins fit standard 1/4" holes. They are the essential hardware for securing trailer tongues, pintle hooks, lawn mower decks, and agricultural implements, reducing equipment downtime with a reliable, tool-free connection.
- Engineered for High Shear Strength: Designed for heavy-duty utility, the solid carbon steel core provides the necessary shear strength to handle towing and rotational loads. These pins serve as a critical safety backup, keeping your coupler latch engaged with the trailer ball to protect your cargo and equipment during transit.
- Bulk 8-Piece Value Pack: This multi-pack provides an immediate solution for fleet owners, farmers, and DIYers. Keep spares in your trucks glove box, tractor toolbox, or RV storage to replace lost or damaged pins instantly, ensuring you are never stranded without a secure locking mechanism.

I use these d-pins for all kinds of projects getting an assortment like this has been a real help. The pins are quality construction and work well for trailers, boat projects and much more. This assortment was a good value vs buying locally.

These hitch pins are exactly what you want in small hardware: reliable, easy to use, and built to survive real outdoor conditions. The zinc‑plated carbon steel feels solid and should hold up well against rust, whether they’re living on a boat trailer, lawn tractor, or farm equipment. The spring‑steel wire locks snap firmly into place and don’t feel flimsy — once they’re on, they stay put. The 1/4\" diameter and 2‑3/4\" usable length make them a universal fit for most trailer couplers and PTO setups. Having eight pins in the pack is a huge plus. These things always disappear when you need one, so keeping extras in the truck or toolbox just makes life easier. They’re not oversized heavy‑duty pins, but for standard trailer and equipment use, they’re more than strong enough and work exactly as intended. Bottom line: dependable pins, clean finish, and a great price for a bulk pack. Perfect to keep on hand for trailers, lawn gear, and general shop use.

I ordered the 8-pin pack of 1/4-inch pins, four with round clips, four with square ones. While they are described as "hitch pins" they are really latch pins, used to keep lever-type trailer hitch latches from opening unexpectedly. Safety pins, in other words. They are not meant as hitch tow pins. But, for use as latch pins, they are perfect, and a good value, to boot. The pins stay with the trailer, but they can be easy to lose, especially when used off-road, like for farm trailers, or a wood splitter. It's always good to have extras on hand, because if you do ose one, it's illegal to tow a trailer on-road without it. I have one small utility trailer that uses one of these pins, and a wood splitter. Sometimes we tow with an SUV, sometimes with a tractor. I'll be putting at least one of these in the toolbox/glovebox of each, so we have on handy when we need one.

These Wellmax Trailer Hitch Pin Set can be used for more than just trailer hitch! They work great for hitch pins, but I also use the square one on my trailer wheel jack and also on my Snowdog 9' plow to replace the locking pin. This set is a good value for the price. They're easy to use, strong, and reliable. Even for more than their intended use!

This is a package of 8 trailer hitch pins, with 4 square and 4 with arch loops. Though the marketing references "heavy duty" the pins are only 1/4" and are more suitable for light duty agricultural equipment depending on how they're used. In general, if the pin is likely to be subjected to significant force when towing, this isn't a good choice. When used to keep the latch down on a trailer's coupler latch, these are more than suitable. This is more of a safety pin than a pin than something intended for a load. These are zinc plated which makes them rust resistant, but not completely rust-proof. There are other types of hitch pins and some are available in stainless steel but for most applications, the additional cost isn't warranted. In my case, the pin is only exposed to the elements while towing a trailer. Once unhitched, the safety pin is stored out of the elements and a hitch lock is installed in its place as a theft deterrent. At about $1 each, these are an excellent value when used as a latch pin. With 8 of them in the package, they're affordable enough you can replace them if they rust over time when exposed to the elements.

This is a great multi-pack of hitch pins to fit different hitches. In my case I was able to test each style to find the one that fit my scenario. The price is very cheap, considering what you get. They have a costing to help prevent corrosion, which is also good. This will also come in handy to keep in my truck just in case something goes wrong with my lockable hitch pin.
