The drilled connectors and fasteners joining my added extrusion to the roof rack.
Why I bought it
Rrina M5 T-Nut and Screw Assortment appears in my build materials and equipment for this work.
Getting the small T-nuts into position took time during my roof-mount work. They could move or spin in the extrusion while I tried to start the bolts.
How I used it in my camper van
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 review
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 Hotop assortment supplies hammer-head nuts separately, while the HOZEON option uses spring-loaded nuts. Buying a combined screw-and-nut kit or choosing the nuts separately changes how the hardware is organized.
Hotop M5 Hammer-Head T-Nuts
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.
These M5 roll-in T-nuts use a spring-loaded design for 2020-series extrusion. Their rounded profile provides another nut arrangement for positioning threaded attachment points in a slot.
