T Slot Bolts for Thule, Yakima 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.

These are well made and stainless steel, checked with magnet, black color also, worked well, I would buy again.

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.

These fit perfectly into the slot of the Thule WingBar EVO. That is exactly what was needed to attach my Overland Vehicle Systems 180LTE awning to the crossbars. It was ordered on 8/2, shipped from Las Vegas to Northern CA on 8/15, and arrived on 8/19. Sold by Moroinriz US.

Save yourself some money and use these for accessories on your TracOne rack from Thule. Great quality.

A little pricey, but well worth it and very durable

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