I have an older Jegs cargo carrier that I used atop our Outback, but the mounts were not ideal for the aero crossbars (they would probably work, but not ideal).I ordered this set of stainless-steel T slot bolts on Amazon. The are a perfect fit for the T slots in the crossbar. They come with the T slot bolts (M6x1mm thread), flat washers, lock washers, and a nut. I added my own fender washers and used 8 of these T slot bolts to attach the Jegs carrier. It is a perfect, secure fit and mounts pretty easily.It takes about 10 minutes to attach it to the crossbars.I am adding a set of self-designed 3D printed knobs with M6x1mm nylock washers for a faster mount and unmount, but these T slot bolts make it all possible. ### ⭐⭐⭐⭐⭐ Roof rail bolts *by on Reviewed in the United States 30 May 2026* These books fit the Rivian R1S / R1T crossbar setup perfectly. No issues installing or sliding them across the bar. Thanks for keeping my older roof storage devices relevant. ### ⭐ Someone can't count. *by on Reviewed in Canada 28 April 2023* The bolts themselves are fine, but there isn't consistency in quantity actually shipped.The listing clearly says this is a pack of 12. The first time I ordered this product I received 5 of the bolts in the package so I set up a return as this was clearly not correct. I ordered the same product again and this time I received 10 in the package.As I only required 10, I decided to just keep the second shipment. If I was to order again, who knows how many would actually be in the package. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/514177224-t-slot-bolts-for-thule-yakima-roof-rack-cross-bars](https://www.desertcart.us/products/514177224-t-slot-bolts-for-thule-yakima-roof-rack-cross-bars) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-08*
