I was trying to mount an old Thule flat top carrier (724 I think) to a Rhino Rack aero bar with the t-channel, which I figured would be as easy as just unscrewing the FM1 (Fat Mouth) clamp from the ski carrier and replacing the clamp with a T-channel bolt. I bought the "M6x35mm, 4mm Thickness" version of these bolts with the fully square base. They are the perfect size and worked out exactly how I wanted them to, using the stock Thule wing nuts to secure them inside the ski carrier. It makes it so someone can't remove the Ski carrier without unlocking it, rather than just by hand with the Fat Mouth clamp. It also saves me about 1" of height on my Jeep which doesn't sound like a lot but can make all the difference in some parking garages. It took me only a few minutes to swap everything. I took the picture after I had mounted the rear rack but before swapping the front rack to illustrate exactly what I was working with for anyone else who was facing the same situation. The other unexpected benefit was that I was able to slide the ski carrier all the way to the end of the bars making it easier to get skis in and out. The second picture shows both racks changed out. ### ⭐⭐⭐⭐⭐ T track mounting hardware. *by on Reviewed in the United States September 28, 2026* They fit perfectly in my t tracks on the roof of my Super Pacific. ## Frequently Bought Together - moroinriz T Slot Bolts for Thule, Yakima Roof Rack Cross Bars, Platform, Cargo Basket, Stainless Square T Track Bolt Adapter to Secure Bike/Ski/Kayak Rack, Solar Panel, Awning - T Track Mount Tie Down Anchor for Roof Rack, M8 Heavy Duty Ring Shaped Eye Bolt, Stainless Steel T Bolt Eye Nut Tie Down Rings for Holding Bungee Cord, Ropes, Hooks - T Slot Bolts for Thule, Yakima Roof Rack Cross Bars, Platform, Cargo Basket, Stainless Square T Track Bolt Adapter to Secure Bike/Ski/Kayak Rack, Solar Panel, Awning, 4mm Thick --- ## 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.jp/products/504953293-t-slot-bolts-for-roof-rack-cross-bars-platform-cargo](https://www.desertcart.jp/products/504953293-t-slot-bolts-for-roof-rack-cross-bars-platform-cargo) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-24*
