These awesome little T-Nuts allow you to affix just about anything ...
I used these to Affix the Rocky Mounts HotRod Bike Racks to the bed rails on my Toyota Tacoma. They are amazig and I wish I would have discovered these years ago. These awesome little T-Nuts allow you to affix just about anything you could imagine to your bed-rails without having to find appropriately sized washers and trying to hold the nut still while threading a bolt into the cobby setup.These things are of a super high quality, and worth their weight in gold!

Exactly what I needed. They fit perfect in my Bed Rails. I have a 2007 Toyota Tundra with stock bed track rails. These T-Slots slip inside them and I bolted my Spare Tire through 2 lug holes on the rim with 2 3/8"-16 Threaded bolts to the T-Slots in the Rails. Works well and still holding.

These were very closely sized, which I like. But, that means your channels need to be very clean during installation, and you might need a quick pass of emery cloth if you fine a burr of any sort

Well if you actually use these in a bed rail you will soon notice rust and then you will likely spend hours researching metal to learn that 1018 steel with black oxide coating (which will scrape off with first screwing) is not what you want for you're automotive application and you'll save your self the aggravation of becoming a metalologist for an afternoon by just buying stainless steal bolts from the start. Other then the rust they are solid and fit in the track well.

Product fits the bed rails nicely on my 2006 Toyota Tacoma. Not sure how corrosion/ rust resistant they are as I just bought them, but I will also not be leaving them in the rails for extended periods of time

The clamps to hold the rack to the bed didn't seem secure so I used a couple of these with some hardware store angle brackets and stainless bolts and it now seems much more secure. The fit and threads are perfect. They're quite heavy for their size and feel very robust

Reviewed in Canada on December 27, 2019

As you can see, these do NOT fit in the Tundra bed rail system. They are way too small and will be set back. Build quality seemed fine, just don't work with the Tundra system.

They measure 22.24mm high.
The stock tie downs measure 25.08mm high.
