Review: Quality T slot bolts - 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 desertcart. 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.
Review: Worked as intended - I bought these to use with my awning brackets on a Rhinorack roof rack and they work exactly as intended. Can’t ask for much more than that.
