Review: Solid T track bolts for most/all T rail systems - 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.
Review: Great oem bolts for Thule racks - Worked perfect for installing my Yakima ski racks onto my Thule bed racks! Worked like oem.

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

### ⭐⭐⭐⭐⭐ Perfect fit for yakima jetstream
*by A***N on May 26, 2025*

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.
