Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this one eighth of an inch cotter pin. This is going to help to secure your castle nut, so that you don't have to worry about that castle nut coming off. So each arm of this pin is about one sixteenth of an inch, so when you have them combined there, it is gonna be one eighth of an inch. As far as our length goes, our overall measurement, we're looking at right two and a quarter of an inch there. Our usable length from the inside of that bend to the shorter arm, is going to be right at, call it one and three quarters of an inch.
So this is going to be made of a rough steel construction so it should do a really good job for you making sure that castle nut stays in place so that you don't have to worry about that coming off. So if you are needing a replacement one eighth inch thick cotter pin, this is going to do a great job for you. You are just gonna get the one pin with this part number so if you need multiple, obviously just increase your quantity. So that's gonna complete our look for today. Again, I'm Michael with etrailer.com, thanks for watching..

It's a cotter pinI had to spend an extra .15 cents to get free

Lauren was very knowledgeable about what parts I needed to pack my wheel bearings on my rv. All the parts worked perfectly.
Seems like good quality pin to lock in a spindle nut
Just repacked bearings with new seals on my 4' x 8' folding utility trailer. Customer service was great in helping me with selecting the right parts including cotter pins. All is good now. I have been ordering from etrailer for 10 + years. Great place with great people!
This was the best cotter pin I ever bought. It was very straight out of the box. It inserted smoothly and was easy to bend but not too easy. After one year it has held its shape and my wheel hasn’t fallen off. I highly recommend this pin and would purchase again.
Etrailer.com staff member told me a product would be a direct fit replacement, the product was not. Instead of making it right I received excuses as to why they couldn’t send me the proper bearing. Disappointed and won’t be purchasing from this website again.
It's a cotter pin. What is there to say.
I am amazed by the detail of the item description on this. There is an actual video of trailer describing the cotter pin, guy even breaks out a ruler to show size. For sure sold me enough to buy two of them, instead of digging through my coffee cans of assorted bolts, screws, to find possibly what I may already have.

I'm glad the video helped so much! I'll make sure to let Michael know that his video helped you :)
Cotter pin worked as expected
I just checked my order everything is there
Won’t be able to install my bearings & races for a while
My package arrived a day early. Everything was well packed and secure. Once again, I couldn’t be happier with the service at E Trailer.
Products are great. Help desk was even better. Helped me get the correct brake assembly for my rv

You had the right size pins for the castle nuts
I sent them a email stating they may want to put the cottee pin in a small ziplock bag and not just free moving in the envelop the shipped it in. As if there had been a hole it would have came out
We have a 2022 Forest River Forester 2551DSLE. Unfortunately it really doesn't come with a usable spare tire holder or a spare for that matter. It had a 4" steel bolt pointing straight down that would be completely worthless. No way I'd be strong enough to get a 75lb tire up there. After lots of measuring this was my only solution. BAL makes 2 products but neither would fit. I mounted 2 X 1" square aluminum bars for the tire to rest against. The winch itself mounted with 2 5/16 stainless hex bolts with nylon topped nuts to keep them from coming loose. The round bar that winches the tire into place uses a 1/8" cotter pin to hold it in place. The hole for the cotter in the bar was drilled in the wrong place so I had to cut off about 1/4" of the tube to get it to fit. I used an original Ford 16" wheel for an e450. The fitting that holds the wheel is about 7". Make sure it is centered as you winch the tire into place. Once up and properly in place it seems secure. Hopefully this will solve our problem of no spare. I would have given this 5 stars if everything would have lined up out of the box. The winch itself seems to be pretty heavy duty and this is the kind of thing that hopefully won't need to be used that often.
Because the pins are not very big, two of the five I ordered had slipped through the holes in the corner of the box, and did not arrive. I suggest that small items, such as these, be taped side by side together on a piece of packing tape. They would be less likely to fall through the holes. Customer service was great though, and will be sending another two.
CORRECT PARTS AND FAST SHIPPING
It is a cotter pin. Did what it was supposed to
Great service, quality products, fast delivery.
Easy to reorder parts for the same trailer.
The cotter pins are very good.
I have been purchasing my trailer wheel seals and cotter pins for many years from ETrailer. Never had a problem.
