It is pretty hard to review a metal pin, but let me hit the AI bullet points... Good quality, good value for the money, it functions as it should (not sure how it couldn't), and it fit in the hole I drilled.

Great item, and it's a good size.I use these all the time, and I'll know how I lose them so often. Something most people with outdoor equipment should always have on hand. Why did you pick this product vs others?: Size and material.

These are great 5/16” pins. I’ve got several tractor implements and these pins are ideal for them. I like these pressure release type ones over others. The pins here all seem well-made and good quality. I’ve used almost all of them and I’ve had no issues with any of them.

Very well made hitch pins, just like the ones I buy at my local farm supply, but conveniently sourced through Amazon. When you own a farm, your tractors and equipment do all of the heavy lifting. These hitch pins are essential for hooking up equipment like bush hogs and discs, and they are ALWAYS getting lost or misplaced. It's nice to have 10 on hand so you know that your work won't have to be delayed by running out to the local coop or hardware store to get more pins before you can hook up and get going. Thank you, Amazon!

The pins are made of a strong steel. They have good weight and work well for what I needed them for, holding a pin in place for a 3point hitch on a tractor. While there isn't a lot to them that is what makes them work well, simple design, strong. I look forward to seeing long term how well they hold up but my anticipation is that they will do the job as described.

Nice, good quality pins and retainer clips. I have a lot of uses for these for my RV trailer, and yard equipment, and home. These are nice in that they are all one piece. No retaining clip to lose.

What can I say? These pins work. They fit everything I’ve thrown at them trailers, boat gear, tractor attachments like they were custom-made for the life of weekend projects and towed adventures. Heavy-duty build, zinc plated, and so far, no signs of rust throwing a tantrum. You get ten in the pack, which means I’ll probably lose nine in the next month and still feel like I got my money’s worth. Four stars for being exactly what they claim to be functional, sturdy, and not trying to reinvent the pin.
