    • Attaching Yakima Skybox to a roof platform using the stock Yakima quick release
Color: M8x65mm, 4pk
Everything came and worked as expected. I have a RhinoRack Recon roof platform on my Lexus GX550, and these fit the T-Slots. I used them to attach a Yakima Skybox. However, I wanted to use the existing interior quick attachment mechanism on the Yakima, and the diameter of these bolts were too large to slide through the stock Yakima system. I was able to drill the Yakima pieces to a larger diameter so that the quick releases work with the T-slots on the RhinoRack. ... show more

    • Great price, sort of works with Thule wingbars.
Color: M8x65mm, 4pk
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. ... show more

After a lot of searching and trying other options that didn't fit, I've finally found some that work on my truck topper! Made my own lightweight cross bar roof rack with aluminum uni-strut and needed a way to attach them to the T slot. This set locks it down well, although don't need all of those rubber washers. Not sure why this set didn't show up in my earlier searches, but glad to have found them! ... show more

    • Too short for my setup, had to return
Color: M6x35mm,6pk
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 price Cons: * Bolts are too short for certain setups * Limited versatility depending on your rack/accessories Who 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. ... show more
