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, M8x30mm, 4mm Thickness

These were a perfect replacement for the OEM mounting hardware on my Thule roof bars for my Grand Cherokee. I thought these were reasonably priced for all stainless hardware.

I ordered a set of Malone aero crossbars for my 2024 Subaru Crosstrek. 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.

Used this for my camper awning install. Worked great to help with updating my camper and the bolts worked for the installing a new awning.

They did what they're intended to do. The edges are a bit sharp, but you could just take a file to them if that's a concern for you. Good and cheaper alternative to the OEM parts.

Worked fine - fit my track. Track is about 3/4 ". Everything down tight - yea.

Installed as channel nuts to secure crossbar solar supports on my Rhino Rack tracks on the roof of my camper. I had to wiggle these a bit to get them past the channel screws holding the channel to the roof, but I am happy with the fit. Nice to have all the extra hardware - a complete kit. Good quality, no issues at all. So far 500 miles and all secure, I’ll check them again in another 1000 miles.

Got this hardware to install a solar panel on my truck camper in the Yakima-compatible tracks. (My existing Yakima rack bolts fit well.) The supplied bolts in this pack that slide into the track are stout and seem well-built, but they did not fit into my tracks. I had to grind out ~1 mm of thickness on both sides with a Dremel tool to get the bolts to slide in easily. Comparing the supplied bolts with the rectangular hardware for my Yakima rack, these bolts are much thicker. The range of washers and lock nuts are great, though, and once I modified the bolts, they worked well to secure the solar panel to the tracks. Make sure your rack will accept these thicker bolts unless you are comfortable grinding metal!

Worked good
