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.

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.

Worked for my application

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.

Perfect fit

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 bought wrong size so I had to grind down to size. This metal is tough and durable. I don't see these ever breaking.

I'm not using this hardware with a roof rack, but rather in the T-tracks on the underside of a rooftop tent platform. These T-slot bolts allow me to mount additional supports in locations where roof-rack cross bars are not available. In my first application, that's the bracketry under a sliding array of solar panels.The 20mm x 20mm square heads of these bolts fit my T-tracks perfectly, also allowing me to fine-tune their placement before tightening everything permanently. Each bolt is provided with a small washer, smaller washer, and even smaller split-ring washer, plus a nut. The bolts themselves are 304 stainless steel; I'm not sure about the other hardware. But I wanted larger-diameter thicker washers, so I replaced everything except the T-bolts with my own stainless hardware.I'm very happy with this order, and recommend the product.
