Perfect fit
Used these to secure loading ramps to the edge of my trailer. Ramps have flat tabs to handle the weight of the ATV being loaded, but no way to secure the ramps from sliding out, drilled a 5/16” hole through the ramp and back edge of trailer and used one of these on either side and solved my problem! A simple bolt would have worked but I enjoy the fact that these can be secured to the trailer for safekeeping even when ramps aren’t attached.

Perfect fit on a 2" Atwood coupler latch
Setting the pin on the bumper and driving off lead me down the path to find a good replacement coupler latch pin. I did some checking on other websites to find the hole diameter that I had and ordered this pin to replace it. It fit great and it is a snug fit with no play. I've ordered a second one to keep in the spare parts box so that if I drive off again with it not in the correct location that I have another one. I do the same with the hitch pins as well. Cheap insurance.

Great price and good pin
Used to retain wheels on John Deere 60d mower deck. Only needed when installing with auto connect. But larger diameter 1/2 inch would be better. But it works
