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

Fit great in a standard truck bed rack rail system. I tried them in the bed rack system and in my roof top tent system and they work well - apparently the "T" bolt system is universal and should work for any "T" rail system attachment you have. Should. The hardware is not Grade 8, but it's sturdy and I was able to get good grip and tightening on it with no movement using the lock washers.

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.

Perfect for replacing the screws on my rhino awning. They are exact fit and longer than the ones that came on the package. The color black looks nice and matches my rack. The bag comes with 12 screws with washers and some extra nuts 🔩. I

M8x30mm T bolts, perfect fit for the Truxedo Elevate Rack T slots! Using these for my Overland Vehicle Systems HD Nomadic 270 LTE awning. Only neg is that it only came with one lock washer and not 6 of them. Can't speak on the hardness, but them seem of good quality.

Worked perfect for installing my Yakima ski racks onto my Thule bed racks! Worked like oem.

Worked as advertised

Looks strong and works for what I purchased them for.

Rusted almost immediately. Fraudulent description.
