The item in my kit
I bought Xadnitu Quarter-Twenty Sliding T-Nuts as part of my camper van equipment.
The light-bar mount made the difference between rack hardware and 2020 hardware especially clear. I bought these quarter-twenty sliding nuts for the larger-thread side of my extrusion equipment.
Where it fits my build
For the light bar, I cut an added extrusion beam and made three short drilled connectors. The rack side used quarter-twenty hardware, while the smaller 2020 extrusion used M5 hardware.
The different nuts changed the assembly sequence. A rack nut had to slide in through an opening, which meant undoing bolts I had already tightened; the smaller nuts could move and spin while I tried to start a bolt. I used an Allen key to reposition them.

My build notes
The cutting and drilling made the components, but positioning the small hardware took its own time. I recorded the difference between inserting the rack nuts and fishing the smaller nuts into place because it affected how the joint went together.
The profile, connector shape, bolt and slot nut all contributed to the assembly sequence.
Alternative products
Two alternatives to compare
The 8020 roll-in nut offers quarter-twenty threads with a different insertion method. The M5 hammer-head nuts belong to the smaller metric profile hardware in my kit; their thread and profile geometry differ.
80/20 3923 Roll-In T-Nuts
These quarter-twenty steel T-nuts use a roll-in profile with a ball spring. Their rounded shape provides another insertion arrangement for 10-series extrusion slots.
These M5 hammer-head T-nuts provide threaded attachment points in 2020-series extrusion slots. Their shaped heads sit inside the channel while bolts fasten the attached parts.
