Video Transcript for Curt Tools - Hitch Tools - C58400 Review

Today we're going to take a look at the 1/2 inch fish wire bolt leader. This bolt leader will help easily pull a 1/2 inch size bolts or other hardware through any hard to access holes in your vehicle's frame. This fish wire tool helps install the trailer hitch receiver, fifth wheel rails, goose neck hitch, or any other items. Basically it lets you guide the bolts and the mounting blocks if required through hard to reach holes in your vehicle's closed train. It'll help position the bolt while you're installing the hitch receiver, the goose neck hitch, or the fifth wheel rails on certain applications. This leader is constructed of a spring steel. Again, the application spreads onto a 1/2 inch diameter sized bolt.

Overall length on this leader from end to end is about 20 1/2 inches. When you go to install it, I happen to pull here is a 1/2 inch carriage bolt that would be used on a lot of trailer hitch installations we do here. Here's a spacer block or mounting block that you would be also used on some applications. Basically there's two different methods. The regular fish wire method would be when you run this wire through the two holes.

Once it's through the two holes you can connect it to your bolt and to your mounting block, if you prefer if it's required. Once you thread that all the way on, and you can pull it through the mounting block, and then this is already through the two holes, so you'll get this to fit through the first hole. When you get to the second hole the spacer block or mounting block would be used to hold it in position and to pull the bolt through the hole and then just unscrew the bolt leader from the bolt. This would be in position in the second hole that you wanted it in to be able to attach your hitch or whatever you're installing to your vehicle. The other way is a reverse pull method. What that is is when you take the bolt and mounting block altogether and go ahead and screw this on the bolt leader to the end of it. You do that first and then you run your fish wire through the hole into the frame, and then pull the bolt with the mounting block.

Again, the mounting block would be used to go get at the support in the frame. You pull the bolt through that hole and in the same way just detach the bolt leader from the bolt. You'd be all ready to go again. That should do it for the review on the 1/2 inch fish wire bolt leader.

Works perfect for fishing bolts through my Lexus frame to install receiver hitch

Make sure you order the right size one of these. I did not know there were different ones. And get 2 or 3 at a time because they will break. I did not know that the hitch I had ordered had come with one of these. Its ok tho, because I needed this one after all. Turns out these things are essential to mounting the hitch. I needed to use (6) bolts. By the grace of God I was able to get 5 of the bolts thru. This thing broke off on the 5th one and I was able to use needle nose pliers to get the last bolt thru. Turns out I could NOT get this to un-thread off the bolt, so each time I had to tug on it to get it free from the bolt. I tried this one I bought for the last bolt, and turns out it was for a bigger bolt and would not fit thru the steel clips. I rigged it and was able to at least get the last bolt thru before this one broke also. I would strongly suggest re-engineering this to be more ductile and "flexible". I was hoping it would flex back to position but that was not the case, Instead it just snaps - sign of wrong material selection.

What great service from this company, I've purchased 2 hitches from them and each time the transaction was perfect. My recent purchase was some extra parts to reattach my previous hitch to my new car (same model 3 years newer). During this global pandemic things aren't moving as fast as previous years and with a holiday weekend, my parts would take longer to get here. Paula went out of her way to get them to me in a few days...not weeks. I was so happy to get them early and excited to get it on my car......but the 108° weather put a halt to that. This weekend it's going on my car and all will be good in the neighborhood. Thanks ETRAILER.COM for all your great associates and products..

Very handy when installing the hitch receiver bar to a 2004 Honda Civic 4-door. Once tightened the bolt a bit too tight - had to do some prying to get it off. Nice that the wire was a bit curved, as it guided itself through the out-hole. I also used a magnet to grab the wire end.

Worked perfect after I got over the operator error (glad I ordered 2). Had to drag a bolt over a frame piece and then into a hole while under my car.

All good see review of trailer hitch. Long and detailed

I ordered the Draw-Tite Trailer Hitch for a 2017 Equinox and it shipped quickly and instructions were very clear for the installation. The Hitch also came with two 1/2 wire bolt leaders and I had ordered an additional one as well. The bolt leaders needed to be connected together to reach from the opening to the guide holes for the bolts. Once connected, that extended the length and it worked perfectly to pull the two center bolts into place. All bolts and nuts fit perfectly. The 1 1/4 hitch works great with my bike carrier and any small carts that I need to pull.

What a difference the right tool makes for an installation of a hitch. It is worth it's weight in gold!



- C58400
by:

These fish wires are amazing. If you did not have these you could not install the hitch on our Dodge Dart; there is no other way to fish those bolts and rectangular washers up inside the torque box to the holes they must be inserted through in order to then bolt the hitch in place. They are worth every penny and worked like a dream.



- C58400
by:

This carriage bolt block was impossible to find locally. Couple this with the bolt leader wire and the how to video on this website and I had zero issues. I was actually amazed at how quickly I was able to fish the bolt/spacer combo into the frame of my car to fix the broken weld but issue. Now all I need is the bolt up the hitch. Thanks etrailer!



- C58400

The Fish Wire Bolt Leader made putting my trailer hitch on much simpler than it would have been without it. I highly recommend this product. I sent back and bought other sizes in case I need them for similar jobs. This is too handy of a tool not to have.



- C58400
by:

Installing A trailer hitch would be impossible without a bolt feeder! 18 inches of wire gave me enough to feed the bolt and flat washer through the slot in the frame and drop it down through the hole into the hitch. Fast turnaround from the time I ordered until I received in the mail thanks George and the crew at Etrailer.



- C58400
by:

Absolutely no way to do the job without this tool. If you have a buick lesabre, get this when you buy your hitch.

It is very handy, having some thing helping in getting a bolt TO & Through a hole in the frame to mount Hitch Receivers. Having an assortment of all the size bolts required is a neccesity.

The trailer hitch receiver kit came with one of these so I ended up not using this, but I tested it out anyways just to get some value out of it and it worked flawlessly. Two thumbs up!

It still works great. I bought a couple extra to be safe. But they are drawing rust because the one I used is still great. Thank you.

I don't typically leave reviews. But my hitch installation was a breeze. Additionally I had to by spacer blocks and a lead wire to use instead of the weld nut. etrailer was super helpful and helped me figure everything out! Great customer service!

This small tool is an absolute must when installing a hitch (size depends on the make of your car/truck). It turns an all day aggravating job into a painless 30 minute one.

Ask the Experts about this Curt Accessories and Parts

  • What To Do if Trailer Hitch Install Weldnut Breaks on Vehicle
    Can you back the bolt out of the weld nut or does the weld nut continue to turn with it effectively preventing it from getting removed? This situations get a little tricky and they are very situational but typically it requires getting the old weld nut out of the way and then using an access hole in the frame to fish wire a new carriage bolt and block in it's place. I attached a link to this page for what to do in your situation for you to check out.

    Both the Curt # C12100 Class II, 1-1/4 inch hitch receiver and the Curt # C13144 Class III, 2 inch hitch receiver use bolts that have a 1/2 inch diameter for the installation.

I have attached a short video demonstration that you can also check out.

  • Can New Carriage Bolt be Fishwired in Place of Broken Weldnut
    If you can access an open end of the frame where the weld nut broke off you could fishwire a new carriage bolt in place of the weldnut. Otherwise you may have to weld the hitch on. Looking at the install instructions for the hitches for your 2012 Honda Odyssey it looks like there are some holes in the frame that could allow a fishwire and new bolt to install. You would need 1/2 inch diameter fishwire like part # C58400. Dirty or corroded weldnuts are typically what cause them to break.

  • Solution for Stripped Weld Nut When Installing Trailer Hitch
    If you can access an open end of the frame where the weld nut broke off you could fishwire a new carriage bolt in place of the weldnut. Otherwise you may have to weld the hitch on or see if a local garage like you mentioned could come up with a way to re-weld in a weld nut. For a bolt leader you could then use the # C58400. I attached a link to an install video that at the 1:30 mark shows how to fishwire hitch hardware. You will need to drill out the old weld nut.

  • Pulling Installation Bolts Through the Frame when Installing Trailer Hitch on a 2008 Ford Fusion
    When installing a hitch that requires drilling on your 2008 Ford Fusion, like the Draw-Tite Sportframe Trailer Hitch Receiver # 24775, you will need to use a little extra force to pull the bolts through the hole that you drilled. When I first started here I helped out installing a trailer hitch on a vehicle and I had the same thought that you did. I quickly found out that if you have enough of the wire threaded on the bolt, you can actually give it a good yank and it will stay on the...

    A broken weldnut installing Curt Trailer Hitch # C13068 is problematic but there is a solution to this so you can finish up the install on your 2014 Honda Odyssey. Like you said you will use another spacer and carriage bolt which you will need to fishwire through the frame with Wire Bolt Leader - 1/2" # C58400.

  • Need Spacer Block to Install Used Trailer Hitch on 2008 Ford Edge
    We don't have the exact spacer block that would've been included with the # C13067 hitch but the # RP3022 comes very close. The block is a little narrower, and the hole is centered rather than being on one end. This means that the block may try to spin once the bolt is being tightened. If this happens, use an impact wrench. The impact wrench will spin fast enough to prevent the block from spinning. It might take a minute or so, but the bolt will tighten. You'd also need a few bolt leaders,...
