Unexpected quality!
Really nice quality. I used them in our 2023 Land Rover Defender OEM roof rack, they fit perfectly into the slots. (Note that you need to peel back the rubber in the roof rack a few inches to expose the widened part of the slot in order to insert the T-bolts, you cannot do it from the edge.)

Quality issues of second order.
These work well and I had no issues installing them on 4WD truck/rack. Everything remains in place!!! My review of the second order was not as great as this one as some of the bolts seized up when using provided hardware!

High Quality, Stainless Steel T Slot Bolts Work Great on Thule Pro Bars
These work perfectly on my Thule Pro Bars. I initially purchased the M6, but opted to go with the M8 bolts for my awning mount as they are stronger. I picked up some stainless M8 fender washers and lock washers to go with it. Works perfectly! These are very nice, high quality T Bolts. Highly recommended!

Bolts are absolute garbage
Bolts are absolute garbage. Extremely soft, even mild torque shreds the threads.
