I saw a guy pull his boat to the lake once without having any pin in there at all !! He says "That thing is so rusty it will never come out." I crawled under his truck and stuck a 1/2 inch bolt in it just to feel safer.

When you insert a hitch into the receiver, you secure it with the hitch pin. Considering receivers and and balls are rated for different weights, has anyone ever seen a rating on a hitch pin?

I can't answer your question, but I can tell you the hitch pin is in "double shear". This is absolute the strongest type of connection that can be made. More than double "single shear".

^ What he said.

And not that it matters, but the shear on a 5/8" pin is nowhere near what gde is saying. It's about 18kips, single shear. So about 36kips minimum in double shear. That's why you see hitch pins bend when not in true shear (like with an adapter sleeve), but you'll virtually never see them begin to shear, but you will see the much softer steel the hitch is made of, egg out the holes. Softer = more malleable.

And yes the etrailer answer guy is wrong. lol

Also why everyone should check/recheck there equipment ANYtime you get ready to GO.

I do a walk away everytime. Habit!


Yes, before you leave. But I like to check every thing just as soon as I stop. Touch each tire and hub for heat. Earlier I find the problem the better.

As for the pin. When you think about the TW forcing the ball mount off-center of the hole, it would take a lot of force to pull the mount out even without the pin.


I check tire/hub/rotor temps with Infrared Temp Gun when I stop....walk around and do a visual then run to the bathroom

upon return I check hookup/connections and just a general look over

Takes but a few minutes and is worth the 'p''p' dance [emoticon]


Is it time for your medication or mine?

I put a zip tie on my clevis pin for piece of mind. At least it keeps clowns from pulling it off, it has to be cut first so creates a simple deterrent and should never jiggle off on its own.
I'm a lock but practically every single thing that can be locked is. I have to travel with 2 ball mounts for the boat one on a stinger with a 2" drop for when the TC is loaded and one with a 6" drop when no camper. Well I had a locking hitch pin on the stinger freeze up. Which is ok since I shouldn't have to ever remove it, the ball ain't coming off either. I had same pin in other receiver at truck. Quit using it out of fear of it corroding shut. Yeah I don't want a locking pin stuck on the truck!

LOL! My bladder is larger than DW's or dog's. We stop, she does the dash while dog and I walk around the vehicle, then to the closest grass. If it is a fuel stop, when spouse gets back, I pull up to pump then go inside. If not fueling wife will stay with truck and dog, maybe fix snacks on tailgate. I don't worry much about tampering, but will look at the paint dots on most of the critical nuts and bolts.
As for the temp gun, might be better, but took my temp gun 1 trip. Put it down to pick up poop. Had to buy new one. I have used my hand with success on much bigger stuff for over half century. If not broke, don't fix it.

Kip :: In the English system, we use pounds to describe weight and feet or inches to describe distance. You may remember that 2000 pounds is called a "ton", but did you know that 1000 pounds is called a "kip"? (It was most likely shortened from "Kilo-Pound") So, when you see a notation like "kpf", think "kips per foot". 0.48 kpf would be equal to 480 pounds per foot. Engineers use kips since it makes the numbers much easier to work with (especially in the days of slide rules) and reduces errors caused by lost zeros.
