The roof frame brought together several threaded connections and small metal parts. This metric threading set belongs to my purchased metalwork kit for working with threads as well as drilled holes.

The item in my kit
I bought Anfrere Metric Tap and Die Set as part of my camper van equipment.
The roof frame brought together several threaded connections and small metal parts. This metric threading set belongs to my purchased metalwork kit for working with threads as well as drilled holes.
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.
