Torx size for bed rails

T25 is way too small, and that's the biggest torx bit I have. The question I'm asking is not about the tie downs, but the rail that runs along the top of the bed. Is it a T30?

 

It should be a T40. @Charvonia Design can confirm as he makes tie downs for our trucks.

 

Did mine awhile ago. Believe it’s T30. It shows T30 torx driver needed tool in OEM Tonneau cover install instruction. I snapped my Snap on torx bit from using Milwaukee impact driver with 4.0A battery.

 

I just checked mine. It's a T30. Note that I have a Bakflip MX4, IDK if that makes a difference.

 

Recently installed a bed cover. I used a T30 to remove & reposition the bed rails during installation.

 

My Tacoma is T30, pretty sure Tundra is the same hardware.

 

100% a T30. I've taken my rails on/off several times at this point.
