Its coiled end securely holds bolts, making tough-to-reach placements effortless and precise, ensuring a professional-grade towing setup every time. ## Description With any towing setup, there is always the need for a few additional items. Though your trailer hitch and ball mount may be tough enough to haul that heavy load, they cannot properly tow without a few supporting players. Towing accessories are a practical addition to your rig that add the finishing touches and take your towing experience to a whole new level. With the right accessories, the difference is a little like cruising the Grand Canyon in a deluxe RV as opposed to camping out in grandma's backyard. CURT fish wires are a special towing accessory to be used during the installation of a trailer hitch. Sometimes, a hitch installation will require bolts to be mounted on the inside of a hollow vehicle frame. The fish wire makes it easier to lead bolts through these tough-to-reach holes by screwing onto the bolt and allowing you to "fish" it through with ease. CURT fish wires are constructed from spring steel and measure 18" in length. This particular fish wire features a bolt coil diameter of 1/2".You never know what obstacles the road before you might bring. The key to overcoming them is to be prepared. From proper safety precautions to quality hitch maintenance, you can count on CURT to have the products you need to come prepared and always Bring It. ## Features - Makes it easier to lead bolts and spacers through tough-to-reach holes - Ideal for installing a trailer hitch on a vehicle with a hollow frame - Coiled end accepts 1/2-inch diameter threaded bolts - Constructed from spring steel for versatile twisting and bending - 18-inch length ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Curt Manufacturing | | Brand | CURT | | Model | Fish Wire | | Item Weight | 0.704 ounces | | Product Dimensions | 7 x 2 x 2 inches | | Item model number | 58400 | | Is Discontinued By Manufacturer | No | | Exterior | YELLOW ZINC | | Manufacturer Part Number | 58400 | | OEM Part Number | 58400 | ## Images ![CURT 58400 18-Inch Trailer Hitch Fish Wire for 1/2-Inch Diameter Bolts - Image 1](https://m.media-amazon.com/images/I/61hoIcjs3ML.jpg) ![CURT 58400 18-Inch Trailer Hitch Fish Wire for 1/2-Inch Diameter Bolts - Image 2](https://m.media-amazon.com/images/I/61TIUoeHY3L.jpg) ![CURT 58400 18-Inch Trailer Hitch Fish Wire for 1/2-Inch Diameter Bolts - Image 3](https://m.media-amazon.com/images/I/71JdP4RbfcL.jpg) ![CURT 58400 18-Inch Trailer Hitch Fish Wire for 1/2-Inch Diameter Bolts - Image 4](https://m.media-amazon.com/images/I/71zDvdeDOjL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked fine *by K***R on July 1, 2025* Messed up the one that came with the hitch so had to get a replacement to complete installation. ### ⭐⭐⭐⭐⭐ I bought this since my last new hitch shorted me these fish wire. *by J***A on November 15, 2024* It took me longer to get the bolts in on my last trailer hitch.
