Purchased for a lost tilt retention pull pin on my 6x8 box trailer. The fit was great and the retention basket should work. Easy to use by just snapping the retention basket over the pin. Secure. Great price in case I lose another one.

As above. Good quality and would have been fine if they weren't bigger than listed, or had I needed a larger size.

They have a secure "click" when they're closed, and it takes a bit of a pull to open them, which is good.

These function well. Not bad quality for the price. Same as the big box stores. Good buy here!

Always good to have a bunch of extras around since they magically get lost every now and then

I like these larger size PTO lock pins. The bail is well constructed and easy to flex on and off. I have a large slide-in truck camper and the bracket extensions for the truck frame tie-downs have little 1/4" lock pins. Sometimes they bend and even break due to the stress of the camper going down the road. I'm going to drill them out for these heavier pins and that should solve the problem. I don't know why the stock pins are so small for such a demanding application. I was glad to find these.

These latch pins are sturdy and well constructed. Their design is such that they shouldn't easily come loose.
