With all the stuff I make and t-track I have installed, almost time to re-order.

Get these for T-tracks
I used to use regular 1/4-inch hex-head screws in T-tracks, and it caused me a lot of trouble. If the head of the screw wasn't completely smooth on all its surfaces, it often dug into the metal of the track, raising a burr and preventing the screw from sliding smoothly. Then I had to spend time with files, smoothing the burrs and smoothing off the screw heads. These T-slot bolts never have that problem. They work smoothly every time, with no difficulty. This is the second lot of 20 that I have ordered, because I needed them. Of the 2 lots of these I have bought, I have had no failures of any kind. Well worth the very reasonable price. Don't try to use these to tie a dirt bike down in the bed of your pickup truck, for dog's sake. They are way undersized for that. As you should know.

Treat them first!
These worked perfect for me to slide into an aluminum channel to bolt town a set of flexible solar panels. I did notice that when matched with aluminum rails you get a tiny bit of corrosion at the joints because the metals are just dissimilar enough to cause that when exposed to weather. I took them out and treated them with metal protectant and haven't seen an issue since. It really helped keep them looking like new even after being outside in the rain all winter. Well worth the price! Hope you found this helpful

Lund Sport Track
Does not fit in Lund Sport Track with out filing, I bought the 1/4 x 20 T bolts to add accessories to Lund boat. After Filing the T will fit into the track system the bolts are fairly soft but strong metal and overall the T bolts will work out just gonna take some extra effort.

T-Bolts, Gotta Love 'Em
Bought these for making a couple jibs for my table saw and router. Good quality, worked perfectly with my existing t-slots and knobs. Recommended for the price.

Nice tee bolts at a fair price but...
the heads are a bit too large. While better than too small I had to grind the heads! I have four different tracks I use these in and they do not fit any of them! Tracks vary in size too and for some these are slightly too wide and for others they are slightly too thick. It is annoying but not a big deal to touch them against a grinding wheel to make them fit. There is plenty of metal so there is no loss of integrity. What puzzles me is why this is so. I have some other tee bolts in a variety pack from Powertec and they work fine in all my tracks without modification.
