I see a lot of complaints about the tnuts.
I see gzilla makes them too, so it’s available elsewhere.
I also see that I can slide tnuts from the ends of the extrusion, so I’m not sure why you would need to use the ones that GFC makes. Am I missing something? I don’t see why people make this a pain point.
Not trying to disregard anyone’s experience; I want to understand it.
Have you found a regular tnut that works with the gfc extrusion? I think the issue is that no one has been able to find a standard slide in tnut that fits. And you can only use slide ins on the sides, the front and rear extrusions don’t have open ends.
I wonder if this could work. Unfortunately, grainger won’t let anyone walk into the store 
with covid and all.
Anyone know exact dimensions of the bolts that fit the t-nuts? I want to replace with a torx bolt to reduce tampering by pesky folk
I did the same and replaced them with 10/32, 3/8 bolts
Thank you, T25 torx head I imagine?
Yeah T25 button heads. Got mine from McMaster-Carr
Just a heads up GFC makes 1/4-20 and 10/32 t-nuts, so make sure you get the correct one
I got t27 but I could find them in 10/32
different t-nuts = pita
I think - the heavy duty things use 1/4
The lighter stuff use 10/32.
