Video Transcript for Using a 1/2 inch Bolt Leader FAQ

All right today, we're going to demonstrate part number 80101-1. This is a half inch bolt leader. Now this part is typically used to install carriage bolts and blocks inside the frame of the vehicle for attachment points for a hitch. We got our hardware here, a typical half inch carriage bolt and a block. We'll go ahead and put those together and then take a bolt leader, also known as a wire pull and put everything together. Now this is the access hole we're going to use, so we'll go ahead and actually take it apart, To thread our bolt through, typically you go head first and then slide the block in. Then we pull everything back through the same hole and that's called a reverse pull. Now the next technique that we show you will be the regular fish wiring a bolt.

Now this is really common. Basically what would happen is this would be our access hole and we'd run this through a hole further up in the frame. In this case, we're going to use these two right close to each other for demonstration purposes. What we'll do is actually take our bolt leader, go through the hole that we want to use, back through our access hole. Then we'll take a block, which typically used, we'll push it in the frame, I like to keep it typically separate, so it can move around independently of the bolt. Plus if there are any obstacles in the way inside the frame, it kind of helps work the wiring.

Then we'll go ahead and take our bolt and put it onto the bolt leader, flip it around again, push it in head first. In certain situations, you may have to work it around like that, just rattle it to get it to work through and then back through the hole you're going to use. There you have it for part number 80101-1.

1/2" Bolt Leader used to fishwire bolts through the frame of vehicles.


This part was lost out of the package. I notify eTrailer and I received one the next day. Excellent service!


It helped me installed the hitch in my vehicle.


Haven’t had time to install hitch yet but going by the video these should be of a tremendous help.


Worked great but wish the lead wire was longer. I had to make an extension


Made installing those carriage bolts a breeze.


I needed his leader to remove the bolts from my trailer hitch from a previous car and put in on my new car. So happy that it was available from eTrailer as I don't know what I would have done if I hadn't been able to find one.
It arrived promptly as indicated when I ordered.


I did not follow the installations correctly and destroyed the bolt leaders that came with my front end hitch. Thank goodness etrailer had these in stock and shipped them promptly. These things are a life saver and work just great!


Worked exactly as needed for my 1997 Wrangler TJ hitch.


well after looking in the box this item was not in the box look like it fell out of one of the handle hole. I will try to reach out to see if I can get these replenished

Sorry about that. Customer Service will reach out to you.

works great

very well

It did exactly what it was designed for. Nice and sturdy.


This tool is ESSENTIAL to fish the bolts through the frame of my car. They made what could have been hours of labor into just minutes. Also, they are more durable than I thought they would be. I ordered two, and only needed one!


Worked perfectly as I was installing my trailer hitch, which is a simple task but ran into an issue. The bolt holes were pretty corroded on the right side so they needed the threads cleaned, with good ole WD 40 I continued to clean with a tap. After getting 2 done the center one weld nut break off inside the frame, as they have very small tack welds from factory holding them on. So I ordered up this bolt, plate, washer, leader, and a nut to fix the issue, it was simple and an easy fix to a problem at first I wasnt sure how I was going to fix. Fast shipping from and it was done ready to be used in a jiffy. Highly recommend

The parts are doing what they were intended to do and super happy with my purchases. If I am ever in need for future vehicles etc I wouldnt hesitate to buy from you again. Thanks again Ryan thumbs up
Ryan T - 01/16/2018


Bolt Leader / Fishwire tool: What a great little product. Worked exactly like it was shown in the video. Blew me away. Nothing works like its shown on video...but this DID.

Only gripe is that the install video makes it seem like it is included with the standard hitch install hardware. It isn't. I delayed my install by a week because it's insane to try it without the fishwire. Worth the wait for me, but order it when you order your hitch.

Its crazy to see all these five-star ratings. I usually think they are bogus. But this hitch kit is the REAL DEAL. The installation kit and fishwire worked just like the video. My trailer is too heavy for lots of use but Im buying a lighter one and then it will get much more use. I am very satisfied.
Gary C - 04/21/2015


One of the BEST helpful products I have ever seen or used! The installation of the hitch would be next to impossible without this device as the size of the bolt and square washer just barely fits where it's supposed to go and if for some reason you need to remove the bolt you can push the bolt back out and start over again! Takes the frustration out of the installation....awesome tool!

Next to impossible to install those 2 bolts without this ingenious device!
Paul B - 06/05/2016


I needed to remove an e-trailer hitch and reinstall it, so I repurchased these devices that let one thread the hitch hold on bolts through the frame. Worked well again.

The wires used to install the trailer bolts are really only used once - whenyou install your trailer hitch. They worked fine.
Cliff W - 01/10/2018


Installation was a nightmare. I bought the bolt leader after watching the video think that was a slick way to get the bolt through the frame. It did not look like the one in the video or the website. The spring material was so thin, it could not erect the bolt inside the frame to be pulled it through the backing plate and frame hole. Had to cut two holes in the trunk of the car to fish out the bolt and get it vertical to drop through the backing plate and frame hole . After that the rest of the installation ( one U-bolt) went well. From the outside, the hitch installation looks good. On the inside, I had to cut plates and seal them over the holes in the trunk to keep the exhaust gases out of the car.


Delivery was fast. Wanted to put hitch on
A different car(same model/year) and not used stressed bolts. Needed spacers and leaders so purchased the items needed from one location,in one box.

Parts worked perfect. Have had good experiences ordering parts and hitches from etrailer
FC - 01/16/2018


Thank you etrailer, customer service and prices are great! Appreciate installation videos & tips. Hitch fit is spot on for my 2003 AWD Rendezvous. Did install in carport by myself without having to lower exhaust or spare tire. Part 80101-1 is a must to make job easier, and 41405 wiring harness is a simple plug in. Will be using primarily for a receiver mounted bike rack.


Highly recommended when installing a trailer made installation much easier, when feeding the Block plate and carriage bolt through the access hole of a 1995 Chevy Suburban's vehicle frame...I would recommend this product...


If you're installing a trailer hitch and don't have ones of these, you're doing yourself a disservice. This makes getting the bolts to go through the frame rails a breeze.

Just a tip, get 2 and it'll make your life even easier. Doing one at a time works, but if you had two I could've installed my hitch in under 10 mins.


I called etrailer to make sure I was getting the right hitch. It was sent out the same day and got it on day 2. The installation was a piece of cake. There installation videos are a big help. I knew just what to expect with no surprises.
I also ordered the 1/2" Bolt Leader used to fishwire bolts through the frame of vehicles. one nifty tool for only 95 cents. I would definitely buy from them again. Highly recommended.


A new-to-me truck meant a
new hitch installation. Needing the mounting hardware for a hitch that I already own, I tried several local vendors for the needed parts to no avail. After a brief internet search, I easily located the bolts, nuts, washers, and fish wire on your website and placed an order. Then, WOW! The level of attention and communication from your staff regarding my order was incredible. The order and the communication was timely, accurate, and thorough. I am now a loyal customer. Thanks for the great experience! Wish me luck in not busting my knuckles during installation.



These little inexpensive items are the real key for making the installation of a trailer hitch a simple process. Be advised that the trailer hitch hardware kit DOES come with more than one of these. At least mine did. The website did not state how many anywhere that I could see so I ended up purchasing 3 extras that I really didn't need. I would recommend calling to check how many your kit would come with if you have any questions about that at all. But they are almost a necessity for a quick and easy install.


no it is not grandma's marshmallow roaster. it is for luring the bolts out of those hidden chassis holes. just screw it on like a nut. i will spare you hours trying to get the bolt to reappear in the hole

  • Using Fish Wire, part # 80101-1 to Install Hitch on 2004 Honda Odyssey With Broken Weld Nut
    The weld nuts can present a challenge. You need to make sure that they are cleaner than clean before attempting to install the bolts. Spray them well with the WD-40, then scrub them thoroughly with a wire brush to remove all road grime and corrosion. Our installers use a wire brush designed to clean battery terminals, which works very well. With the broken weld nut, you will have to cut the bolt off, and use a 1/2 inch grade 5 or better carriage bolt to replace the bolt you have cut. You...

    Since you have broken weldnuts the only thing you can do is use a block and carriage bolt, drop them down through the frame using the fishwire technique with a bolt leader like # 80101-1 and then use a nut to secure the hitch to that bolt. This is assuming you do not want to go through the trouble or expense of having new weldnuts professionally installed in the frame. If you do this you will need bolts that are grade 5 or better, the same size as originally included with the hitch and...

These are used to install bolts and washers inside of the trailer frame.

    Yes, it sounds like you broke something. Specifically one of the weldnuts that are on the inside of your 2019 Honda Odyssey's frame for the trailer hitch's bolts to thread into. It's annoying but not really a huge problem. Although it'll probably cost you a trip to the hardware store. You need a Grade 8 carriage bolt and a washer, nut, and spacer block that fit it. You also need a bolt leader, part # 80101-1. You're first going to need to get the bolt out by breaking off the head....

    Since access to the frame is blocked on your 1996 Ford Bronco what you can do is fishwire in the bolts and spacer blocks by using a large enough access hole for the frame or, if no hole exists, you could make a hole through which to run the bolts and blocks using fishwire # 80101-1. I have linked a help article that has a section that explains fishwiring. Looking through the other hitches for your Bronco all of them attach to the bottom of the frame rails in the same manner so if fishwiring...

  • Solution for Broken Weld Nuts Installing Trailer Hitch on 2012 Honda Odyssey
    Did two of the weldnuts in your trailer frame brake as you were tightening them down?

It's a fairly common problem that we see and because of that we made an FAQ video on how to address this problem. Check out the video I attached to the right to see it. You will need a bolt leader like part # 80101-1 as well.

  • How is a Bolt Attached to the Fishwire?
    You would need wire that is flexible enough to wrap around the bolt threads without coming loose. Annealed Stove wire works great. We also offer the fish wire in either 7/16 or 1/2 inch size. The part # for the 7/16 size is 80103-1. The part # for the 1/2 inch size is 80101-1. The bolt would actually thread into the fish wire.
