Starting Small Screws While Keeping the Slot Nuts in Place
I made drilled connectors for the added light-bar beam.
I used quarter-twenty hardware at the rack and M5 hardware at the smaller extrusion.
When small slot nuts moved or spun, I repositioned them with an Allen key so I could start the bolts.

My Takeaway from This Job
Getting the threads started took more handling than the finished joint suggests. The choice here is separate short screws, screws and nuts together, or a bracket kit that also supplies the connecting plates.
The profile, connector shape, bolt and slot nut all contributed to the assembly sequence.

The low rounded head sits on the exposed face of the connection, while the M5 shank reaches the nut inside the slot. My roof-frame work made access to those small threaded pieces important during assembly. For a van extrusion joint, record the plate thickness and actual screw length with the selected nut. Include space for the hex bit above the head, especially where a neighboring rail or a fitted panel will later obstruct the driver.
Keep the screw length, plate thickness, slot nut and actual profile together in the joint record.

Two Alternatives to Compare
The Rrina set groups screws with slot nuts. The L-connector kit adds plates as well, offering two ways to buy more of the joint hardware together instead of separate screws.
This assortment combines M5 screws with hammer-head slot nuts. Its grouped hardware provides fastening pieces for slotted aluminum-extrusion assemblies.
