Wet Equalizer Bolt with Locknut and Grease Zerk for Double-Eye Springs - 3" Long
The wet bolts were just fine. But the "locking nuts" with the crimped edges were aweful. The 3 dimples each nut has were not useful. Many of the nuts I could use my fingers to spin them on the bolts. Never had locking pressure. I ended up going to local hardware store for much better locking nuts.
I used these "wet" bolts on my leaf spring change out. I ended up using 3 per equalizer since that seems to be the location of most of the movement during axle travel and a friends 5th wheel had 3 installed on the factory set up, so that is what I went with. I painted a yellow mark on the head of the bolt in reference to the grease hole in the shaft, so that I could install them in the direction of "least resistance" when greasing them later, after reading how some guys have to relieve pressure on their trailer in order to get the bolts to take grease. I used Mystik 6 grease mixed with anti seize when putting everything together, then gave them 2 shots of Mystik 6 after installation. (I chose Mystik 6 because we always had good results with that grease when I was in the aircraft industry and it doesn't was out.) I did notice that the grease zerks did allow grease to return out of the fitting which means the spring behind the ball isn't doing its job. That is why I rated them as "good". There are different ways to install these due to the knurled shoulder. If you have access to an impact gun you can just tighten them in with that. Pulls the knurl right in to the shackle. Overall I like the idea of having a suspension that can be greased.

Zinc Shackle Bolt with Locknut for Double-Eye Springs - 3" Long
Parts are a 5, delivery options questionable.Can't delivery 10 pounds of metal in a paper mailer. Was tore open on the bottom. I run a mailing business and I can tell you its not that much more expensive to use a box.
New bolts made replacement of springs easy

Shackle Bolt with Locknut for Double-Eye Springs - 3" Long
I needed it quickly because on stripped on my trailer and we were getting ready to leave the state in our Wold Pup. I paid for the extra shipping and they got out and to me in 2 days. Thank you.
These are the exact bolts used by the manufacturer of my trailer. I had a spring break after 10yrs use, so am replacing the springs and all the bolts at the same time, thank you to etrailer for the springs (ordered earlier) and now the bolts/nuts, all arrived quickly and accurately, you are my first choice for all trailer parts for my 7 trailers, thank you and keep up the good work!

Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long
Just what needed for my trailer. My old leaf springs were so rusted that I was one pot hole away from being broken down on the side of the road. These new ones are perfect.

Wet Equalizer Bolt with Castle Nut, Grease Zerk and Cotter Pin - 3-1/2" Long
This is an excellent product, but I gave it four stars because it was nearly impossible to install with ordinary tools. It was necessary to force the serrated portion into the center hanger and since I did not have access to power to run a compressor and force it into the hole using excess torque via an air wrench, I had to use a hammer to drive the serrated end into the hanger. I found an install video from etrailer that showed how the installation was to be done, but I could not accomplish it that way. Besides the amount of torque needed would probably have twisted the bolt off at the grease hole. As it was, I drove the part in with a 3# hammer after destroying ordinary white wood blocks of wood. I removed the grease zerk and used another piece of flat iron to protect the zerk's threads. I was able to bottom the head against the hanger by tightening the nut as much as I could by hand and then hitting the head with the hammer a few times, tighten again, etc., until it was completely in place. This method was used on both sides of the trailer. To torque these into position with an ordinary wrench would have exceeded 1000 lbft of torque which I am not sure that these bolts would take without damaging them more than the hammering did. To be fair, the information suggested that the hangers be replaced, but that was because many times the hangers are damaged if the other parts wore out. But it is fairly clear that the holes in the hangers are not pre-formed with matching serrations so I doubt that it would have changed the issue. In short, I don't believe that the serrated portion is necessary. And if it is, then a keying method would be more appropriate, such as a square hole.
Purchased replacement springs, equalizers, shackles and all the needed hardware to put it all together for my tandem axle boat trailer. While I was trying to figure out all the parts I needed on-line, I made a couple calls to etrailer's customer service and they were awesome! Parts arrived quickly and are exactly what I needed. I put together one of the spring / equalizer / spring set-ups and placed it on the trailer frame to confirm fit. Perfect! Looking forward to swapping all the parts out this weekend. And I'll be shopping with etrailer again soon to get a trailer hitch for my new Durango! Thanks etrailer!
