Video of Shackle Bolt with Locknut for Double-Eye Springs - 3" Long
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Today we're going to take a look at the 3-inch-long shackle bolt with the lock nut for double-eyed springs. This bolt will secure leaf springs to your front or rear hangar of your trailer's suspension system. Does include this lock nut to secure the bolt into place. Now the bolt itself is a grade-5 bolt. The overall length on this bolt if we measure it from the bottom of the head to the very end and see is going to be right at 3 inches. The bolt size is a 9/16th diameter by 18 threads per inch. The bolt head size is 13/16ths of an inch.
I got example here's a socket. You can see it will fit the head perfectly and then the lock nut which goes on the end right, the size on that is 7/8ths of an inch. You can see it fit rights into a 7/8ths inch socket but that should do it for the review on the 3-inch-long shackle bolt with the lock nut for the double-eyed springs.

9/16" Diameter spring-retainer bolt is used to mount double-eye spring inside front or rear hanger. Includes locknut.Awesome.. Simple to find what I needed, quick delivery and parts ordered were a perfect fit for what I needed. Will use every time! Thanks etrailer.com 513967
Well, I just got the parts, so can't say anything reliable on chinese made parts. The price was(is) Great! a boat load cheaper then the local store....humm. springs fit perfectly, however, the springs I wanted are no longer being offered, could of had springs made but I went with the less$isMore theory. (more in my pocket) The "white" nylon bushings I ordered would not fit into the equalizers, but the grey colored ones I had did fit perfectly, just a-hair difference in outer diameter. The bolts fit perfectly as well. It is always 10 times easier dealing with eTrailer then the local store, So I know eTrailer has put a lot of time into making it easy for their customers, Thanks! Very Fast shipping, all at a price I can afford! 355949
Product was just as advertised. Quickly shipped and received in time. Packaging was very well done and organized well with everything there as ordered. My only disappointment was to see the words "CHINA" written in bold letters on my springs. I'd much rather have seen USA. 379590
Thank you for following up. All is good with the products. No issues so far.
I fixed my 5 wheel today with all the parts I got from you changed,all the equlizers and the shackles on both sides,my fifth wheel camper was blowing tires left and right.the shackles were almost wore all the way through the the end of the shackle.the tires were out of line with a straight line by two inches,when I got the new parts on the tires were right in line.thanks for the great prices and your web sight was easy to use and fast shipping I will be ordering from you again.thanks ron 213398
The equilizers worked great I havent blown a tire yet thanks for all your help Ron
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! 548557
Well made, hard steel, good threads. This bolt/nut set is more expensive than local no-name bolts, but is of superior quality. 264423
No failures to date. A coat of primer on the ends controls corrosion.
Never a bad experience working with etrailer. If something goes wrong (which is rare) whether it's their fault or not they always make it right. I'm always confident in their products and trust them in my purchases. 724925

Great parts, excellent service and fast shipping. This is the only place to get trailer parts as far as I’m concerned! 707566
Bryan w worked with me to get what I needed, all parts were available and I received shipping information despite my order being made late in the afternoon. Arrived ahead of expectations. I'll be able to work on my trailer this weekend. Very pleased with the results this far! 713241
Very good value. Broke Springs on a small center console tender trailer, thought OH boy how am I gonna find parts for this. Searched on-line. Found etrailer and BAM = problem solved. Got springs, shackles, bolts, even an entire spare and tire for a couple hundred bucks and THEY ALL FIT and at least as good quality as the thing was build with. Excellent and pretty quick shipping and delivery for heavy stuff. 711537
Perfect fit. Good experience! 703687
Just what was needed. Hardened bolts for my trailer springs. 703005
I had a trailer spring break this summer on the way home from a 2,700 mile trip. Our small luggage trailer just couldn’t take anymore rough roads. One of the springs broke through the centering bolt. The etrailer.com website and Tammie P. came through with replacement springs and accessories. Thank you Tammie P. And trailer.com! 703496
I don’t recommend these. I had a big issue getting them in without damaging the fine threads. The knurl by the bolt head made me have to use a hammer which I didn’t think I was gonna need. The other issue was that once I tightened the nut ait don’t come off. And had to cut a couple of the $4 bolts replace a few things I missed while fixing the axle/suspension. I ended up going to local hardware store and just replacing all the bolts I purchased with higher grade for even cheaper. 699352

Hi folks, parts arrived in a timely fashion, haven’t put them on yet but look like quality parts. Also the fenders I ordered from you were very nice. My friend welded them on for me and they look great all painted up. The fenders were of good quality steel, and I liked the fact they were made in the USA. Thanks etrailer. Gary T 681484
The product works as expected. Will use u again when I need trailer parts, thanks 673221
Shipping was great everything fit well I have no complaints 669863
I bought springs, shackle bolts, and u-bolts and plates. Everything was great and fit perfectly. Only issue were the u bolts which were not galvanized. However, at a local trailer store, I bought galvanized U bolts for $4.50 each. For the DYIers, taking the old ones off took more than 4 hours for each side. My existing shackle bolts were so heavily rusted that I had to cut three off with a hack saw. Difficulty was confined space to operate hack saw with boat still on trailer. However, reassembling the new springs was less than 45 minutes each side. Must have tools are large diameter 3/4-13/16-7/8 deep sockets (6 point), 2 2 foot long breaker bars and a can of PB blaster. For safety: Good quality jack stands, minimum of 3--don't rely on the front trailer jack as it may roll. By the way, I did these myself and I am 64 years old. 667342

Good quality and fast service. Great service. Thank you 653406
The bolts are excellent. I used these bolts in conjunction with links to connect the springs to the equalizer and to the hangers. They worked very well except that I could not apply enough torque to the bolts to pull the serrated end into the links. In each case I had to apply considerable force to the head in order to get the serrations into the links. I did not have a large enough air wrench to achieve the necessary torque and using a wrench required an excessively long handle. (I did not have electricity to run an air wrench.) So I was forced to alternately tighten and then drive the head with a large hammer (3 lb) against another flat piece to drive the bolts in, then tighten again until the heads were set. This makes me question the need for the serrations (the original bolts were also hard to remove). A square hole might be better - similar to a carriage bolt. 652878
Product works perfect 647491
I bought a used Jon Boat trailer and first time out the shackle bolt gave out. Perfect fit for my application and I really like the way the nut was made so that it locked on the bolt. I used these with the Never Fail Bushings. I had to drill out the shackle to accommodate this beefy bolts but that wasnt a big deal. I ended up doing both sides that had standard bolts instead of wet bolts. Not sure why only 2 were regular 3/8 inch bolts. 642554
