Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the three inch long, 9/16 diameter Zinc Shackle Bolt with the locknut for your trailer leaf springs. Now, this 9/16 diameter shackle bolt is used to mount your leaf spring to your trailer's front or rear suspension hanger, and this part will include the locknut that secures the bolt to the hanger. Both these parts are a corrosion resistant zinc finish. This is for a quantity of one bolt and one locknut. Now, few dimensions, we'll start with the bolt itself, we mentioned the diameter on this, it's gonna be right at 9/16 of an inch.
The bolt head size or the socket size you would use on this, it's gonna be 13/16 of an inch. Now, the length under the bolt head to the very end of the bolt is gonna be right at three inches, the usable length, which would be from under the bolt head to where the thread starts, is 2 3/8 inches, and just the thread length is about 5/8 of an inch. Now, the thread size on this is 9/16 by 18 threads per inch, and the lock nut, which will install right on here, when you go to install it, that's gonna have a diameter or head size of 7/8 of an inch. But that should do it for the review on this three inch long, 9/16 diameter Zinc Shackle Bolt with the locknut for your trailer leaf springs.

New bolts made replacement of springs e asy
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.
Ideally, the shoulder of the bolts should be long enough to extend all the way through the spring and shackle so that the threads are not subject to load or moving parts. The treads are the weakest portion of any bolt and should only be exposed to tension, not sheer loads. This being trailer hardware, I guess that design factor is not a high priority. Just seems like it could be done right with just a smidge more effort or consideration. That said, the original bolts I removed had only a slightly longer shoulder and one-half the shackle was riding on threads and it held up for years, although it was worn considerably more in the threads.
What can I say they are bolts they are still bolted in!

They seem good. These and shackles need to be checked every season or two.
Wth rusted out leaf springs on my trailer but with zero experience replacing them, I contacted etrailer and Shawn was very helpful in selecting the right parts and taking me through the process. She was patient in terms of helping me take the right measurements and suggesting the bolts and pieces I needed to do the job right.
Everything came well packaged and complete two days later. An hour after that the springs were in my trailer and now has a boat sitting on it.
Thanks!
We appreciate your great service!
I have not been able to use parts as UPS lost one entire shipment, damaged another shipment and etrailer left some parts out of the replacement shipment. I want to replace all the items on my trailer together in one day.
Anyways, your company has been good about fixing the issues.
I hope UPS pays for the damage and lost shipments.
we plan on doing more business our trailer seem to be a hit see attached photo
Serrations did not get a good bite into bracket.
