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.

The trailer has since been on a second cross country trip and it is still working just like it was the day I finished it.
