Reviews
"Used in the 2013 Tacoma track system."
"I would be happier with a t-slot nut that had bigger shoulders because it would fully engage the rail without risk of pulling out or going crooked."
"Bought some 3/8-16 threaded I bolts to screw into the T-slot nuts and now have more tie down points on my truck bed."
"Had to take them to the work bench, put them in a vice, add some WD40 to the threads, and use a ratchet and bolt to clear the threads."
"I have a 2007 Toyota Tundra with stock bed track rails."
"These are a perfect fit for my Tacoma's bed rails -- I've used two of them for home-built jack hangers, and will use the other three for hanging other useful emergency items."
"a bit expensive, for what it is, but i wanted to be sure i got the right size for my new tacoma."
"I used these and a mirror antenna mount to mount an antenna to my bed rail."

"The only problem was I received 20 instead of 24, and I didn't find this out until me and the technician employed at my job started installing them on my truck - my bad for not counting them when I opened the box (I was more concerned about the fit, which I was able to check quickly because I had to replace a stripped wheel lug, which was damaged when I taking some of the old wheels nuts off when I had a change out a spare tire on the right rear)."
"I went out to my local auto shop, you know the regular Autozone, Oreilly and such. Oh and btw I bought this with no Prime shipping, I was expecting a 4 days shipping but to my surprise the package showed up in 2 days! For the price you won't be able to find a matching set at your local store if you can find a 20 piece set."
"Perfect, the cheap Chrysler lug nuts had plastic caps or cheap metal glued and pressed to a stud which sucks absolutely when in emergency and trying to take out lug nuts."
"Really great deal ... factory lugs had started peeling off the chrome caps and ended up having to have one of them cut off so I purchased these to replace all of them before another one messed up."

"I've used the heck out of these and haven't found a decent source for the individual spacers/standoffs."
"My evaluation of what I received is that all the white items fit each other while the black posts are quite variable, many not fitting the others, nor the black nuts and screws, very well. It is good that the black nuts and 5mm long black screws fit the white items, (as well as fit each other). There are 60 black screws, and 60 black nuts, meaning plenty enough for most of the posts in the white collection. I wondered why the black posts are such a poor fit, and guessed that maybe the black screw ends on the posts were too large a diameter."
"Almost perfect size for spacing add-on boards, the size that worked is just 1mm too long, but that doesn't interfere with the connection."
"I needed these stand offs for my quadcopter flight controller."
"If you're getting into building drones, don't even hesitate."
