T Slot Bolts for Roof Rack Cross Bars, Platform, Cargo Basket, Stainless Square T Track Bolt Adapter to Secure Bike/Ski/Kayak Rack, Solar Panel, Awning, 4mm Thick

Bought this to mount a car awning i bought from amazon. This T slot bolts save my crossbar from being drilled. The washers that came with is was a plus, held everything together. Easy to use and fit perfectly in my yakima crossbars.

Perfect fit, exactly what I needed.

Holds truck rack in T-Slot rail perfectly. Finish is nice, no rust yet after several months near the water.

I'm only giving 4 stars because these pieces despite likely solving a problem, could have had a much better finishing job, and then I wouldn't have had to modify them. I'm also not able to review the strength of them, but they look solid..I'm installing a ski/ roof box requiring 8mm thread T- bolts on Thule Wingbars bars. Thule Wingbars are made for T-bolts with smaller heads. The standard Thule is 6mm thread and I have not been able to find out if Thule even makes an 8mm version?So, I ordered these since I didn't want to modify the Roofbox factory 8mm T-bolts with heads too large for the Thule wingbars, keeping them stock in case I ever sell the ski/roofbox.I also wish these T-bolts came in other lengths, since I had to cut off about 10mm, to make them work for my application, but that's not a reason I only give it 4 stars.Reason for the 4 star review is that the base/head of these T-Bolts is just an unfinished stamped square piece of steel with a black finish on it.Head has sharp edges, and to make sure I don't damage the rubber seals/ trim. To make them easier to install, not jam when sliding in the track, I had to use my Dremel to carefully remove the sharp edges of the heads of the bolts. With beveled edges, they work way easier in the track too.I would gladly have paid twice as much, to not have to do this.Lastly, like others have noticed, the stainless steel used has a very light attraction to strong magnets. Because I had to remove metal, I was wondering if those areas might be prone to pitting/ corrosion, or if there is enough chrome in the 304 alloy to resist it.So after removing the sharp edges, I left the T-bolt in a light salt bath for 24hrs and it didn't create any visible rust stains. I still gave the pieces a hot oil bath, and I'm thinking they will be ok. Not have any rust issues to worry about.

Perfect for Toyota LC 250 roof rack. I was they came with all 12mm nut my set had four 13mm and two 12mm.Used the to hold a 57 LBS awning to the side of my roof rack. Had no issues even with lots off road bouncing held tight.

Key takeaway: Didn’t work for my setup. The bolts were too short, so I had to return them.Real usage experience:Tried using these on my roof rack cross bars, but the bolts didn’t have enough length to properly secure anything. Fit into the T-slot was fine, but they just didn’t extend far enough to be usable for my setup.Pros:* Fit into T-slots without issue* Threading seemed fine* Decent quality for the priceCons:* Bolts are too short for certain setups* Limited versatility depending on your rack/accessoriesWho it’s good for:Might work if you have a low-profile setup or thinner mounting points. Not ideal if you need extra length for platforms or thicker accessories.Comparison:Compared to other T-slot bolts I’ve used, these run shorter than expected. I’ve had better luck with longer variants that give more flexibility.

Great bolt does everything you ever wanted a bolt to do! It’s the boldest bolt I have ever used!

Worked perfectly for my Thule Winged Evo and bike mounts

Für die Unterkonstruktion eine Kanuhalters benötige ich eine zuverlässige verbindung in die Aufnahmeschiene meiner Thule-Traversen. Die hier vorliegenden Nutensteine sind hierfür genau richtig. Sie bieten ein ausreichend dimensioniertes M6-Gewinde, um auch durch 3cm MDF-Platte noch ausreichend Restgewinde für die Verschraubung vorzuhalten. Einziger Wehrmutstropfen: Die Aufnahmeplatten sind unten nicht abgekantet, das erschwert das Fädeln. Ich werde hier mit dem sSchleifer nachhelfen müssen. Abgfesehen davon: Top-Basis für ein Selbstbauprojekt. 4/5 PunkteAnmerkung:Das hier rezensierte Produkt wurde uns im Zuge des Amazon Vine-Programms kostenlos zur Verfügung gestellt.Dies hat keinen Einfluss auf meine Bewertung.

I’m very happy with this T slot bolt accessory kit — it has worked perfectly for securing various gear attachments to my roof rack’s T-track system. Whether I’m mounting a bike rack, kayak rack, cargo basket, awning, or solar panel bracket, these bolts have been solid, reliable, and easy to use.The stainless steel construction feels durable and strong, and it’s reassuring to know these bolts are rust- and corrosion-resistant even in harsh weather conditions or salt-water environments. That quality gives me confidence that they’ll hold up over time for camping, touring, road trips, and other outdoor use.Installation was straightforward — the bolts simply slide into the T-track on my Thule-compatible cross bars, and they tighten securely with the included nuts and washers. Everything fit well and held tightly, so I haven’t had any loosening or movement once mounted, even on rough roads.One thing buyers should be aware of is that these bolts come in different sizes and configurations (e.g., M6 × 35 mm, M8 × 30 mm, M8 × 65 mm, various pack counts). It’s important to measure your carrier’s T-track dimensions or check manufacturer specs before ordering so you get the size that works with your roof rack system. Once you’ve selected the correct size, though, they fit perfectly and function exactly as intended.Pros:Works very well for attaching rack accessories securelyDurable stainless steel that resists rust and corrosionEasy to install and tightenGreat value for a multi-piece T-track bolt kitCons:Make sure you pick the correct size for your specific carrier/T-track system; otherwise they might not fit properlyOverall, this kit worked really well for my setup and has been dependable for all my rooftop gear mounts. Highly recommended for anyone with Thule, Yakima, Whispbar, Rhino, or other compatible T-track roof rack systems — just pay attention to the size you need before purchasing.

Fit the bolt track on the running boards of my truck perfectly. Had to take them off to refinish and the bolts were corroded from our lovely Canadian winters and salt so they came off in two pieces each. Needed these replacements desperately otherwise it was buying a new set of running boards. Good value for me.
