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.

Works great, used to secure a Thule ski box. I also purchased thumb screws so I don’t have to use a wrench to tighten hardware.

Stainless steel is the way to go on my Yakima lock n load roof rack.

For the price, this is an excellent Thule replacement t that arrives fast and works. I lost a Thule bolt and needed a fast replacement before the weekend. As shown in the picture the replacement t does not have knocked down corners nor chambered edges, but they still work.

A little pricey, but well worth it and very durable

Bolts work great on my ARE Roof Rack

These worked well for adding a wider platform for hauling 2 canoes on my Thule Trakrack truck rack.But are they really stainless steel? Photo is after about 2 weeks in use with Montana rain the only liquid they saw.. 304 isn’t the best grade for corrosion resistance but I am skeptical these are stainless at all. I’ll keep them but seller should consider changing their description.

I used these on my yakima jetstream load bars to install a yakima sidewinder tandem rack. I went with the 8mm as it seemed better suited to the higher potential load of this combination. I did 3d print an insert to make the nuts removable without a tool. They seem to be very high quality and have yet to show any signs of rust.
