Jeff: Hello, everybody. This is Jeff at etrailer.com. Today, we're going to take a look at the 9/16th diameter, 3 1/2 inch long spring eye bolt with the lock nut for slipper springs. Now this 9/16th diameter spring retainer bolt is used to secure the slipper spring to the front hanger of your slipper spring trailer suspension. The 3 1/2 inch long bolt is common on trailers that have a 6,000 pound or 7,000 pound axle and uses 2 inch wide leaf springs.Now, the bolt itself is a grade five bolt. The way we can tell that is, if you look at the head, you'll see three lines on it.
That'll indicate that that meets the grade five designation. The length on this is 3 1/2 inches, and that's measured from under the head to the end of the bolt, so there's your 3 1/2 inch length. Diameter of this bolt is 9/16th of an inch. The thread size on the end here that the lug nut or the block nut attaches to is 9/16th by 18 threads per inch. Now the bolt head size is a 13/16th of an inch, and let's show you here's a 13/16 socket.
Oops, wrong one. Here's the 13/16 size socket. You can see it fits securely on there.And the lug nut size uses the 7/8th inch size socket, and that's the first one here I pulled. And you can see that fits exactly on there. And this included lock nut is what will secure this bolt to the spring eye.
But that should do it for the review on the 9/16th diameter, 3 1/2 inch long spring eye bolt with the lock nut for slipper springs.

We run a farm operation with multiple pieces of equipment. Etrailer's prices and prompt service saved us a great deal of time and money. The pictures with specifications is a serious help. Definitely will be ordering from them in the future.
I just received and installed the spring hardware I ordered from etrailer and I must say I am well pleased. Shipment was prompt and the parts were exactly what I needed and at a great value. I was pleasantly surprised that my order was processed and shipped so quick being a small order. I will definitely use etailer again.
Happy towing!
Fast shipping and very thorough communi cation.
Great Experience!
When I noticed that the leaf springs on my 44 year old boat
trailer had cracked I thought I would never find replacements.
I fully expected to have to have something custom built.
I was amazed when I found the fantastic diagrams/descriptions
dimensions for replacement springs on etrailer.com
The phone support person was wonderfully helpful in confirming
if items were in stock and ready to ship. The replacement springs
arrived on time and everything bolted up perfectly!
Thanks for such a great site!
Nice hardware. The video on the site is fairly clear about installation, but it could be more straightforward and tell you to put the nuts on so that the little “dings” that make these locknuts are to be on the “outside” of the connection. That is, you’d see them once installed. Also, depending on the exact size of the 9/16 eyehole you have you must do some serious hammering to seat the bolthead properly with the fluted bolt.
I have bought many different products from Etrailer and the staff have been more than helpful and I would recommend this company.
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.
I will be disassembling and do a further visual coming up. But what I did see while on the trip is that it definitely looks as the rollers (gold colored like a grade 5 - 8 bolt, I'm assuming they are hardened) that are in the system to roll on the slipper springs are showing wear.
Very happy
I have purchased a number of items from etrailer.com such ans leaf springs, axle and hub assembly, and other items as well, I recently finished the trailer and it is now on a cross country trip. The trailer has just finished a 3,000 mile leg of this trip and I am told it was so smooth that it could not be felt by the towing vehicle.
Every product I have ordered from etrailer.com has been top quality and has worked extremely well. I would come back again for any of my future trailer needs.
